1)  

 Find the cost of levelling a square park of side 20 m at 7 per sq.m.

Answer: 2800


SOLUTION 1 :

Given   :

The side of the square park   =   20 m

 For finding the cost of levelling, we need to find the area and then multiply it by the rate for levelling.

Area of the square park   =    Side x Side

                                              =    20 x 20

                                              =  400 sq. m

Cost of levelling 1 sq. m     =   7

Cost of levelling  400 sq.m = 7 x 400

                                               =  2800



2)  

 Find the cost of levelling a square park of side 20 m at 5 per sq.m.

Answer: 2000


SOLUTION 1 :

Given   :

The side of the square park   =   20 m

 For finding the cost of levelling, we need to find the area and then multiply it by the rate for levelling.

Area of the square park   =    Side x Side

                                              =    20 x 20

                                              =  400 sq. m

Cost of levelling 1 sq. m     =   5

Cost of levelling  400 sq.m = 5 x 400

                                               =  2000



3)  

 Find the cost of levelling a square park of side 18 m at 7 per sq.m.

Answer: 2268


SOLUTION 1 :

Given   :

The side of the square park   =   18 m

 For finding the cost of levelling, we need to find the area and then multiply it by the rate for levelling.

Area of the square park   =    Side x Side

                                              =    18 x 18

                                              =  324 sq. m

Cost of levelling 1 sq. m     =   7

Cost of levelling  324 sq.m = 7 x 324

                                               =  2268



4)  

 Find the cost of levelling a square park of side 15 m at 3 per sq.m.

Answer: 675


SOLUTION 1 :

Given   :

The side of the square park   =   15 m

 For finding the cost of levelling, we need to find the area and then multiply it by the rate for levelling.

Area of the square park   =    Side x Side

                                              =    15 x 15

                                              =  225 sq. m

Cost of levelling 1 sq. m     =   3

Cost of levelling  225 sq.m = 3 x 225

                                               =  675



5)  

 Find the cost of levelling a square park of side 18 m at 4 per sq.m.

Answer: 1296


SOLUTION 1 :

Given   :

The side of the square park   =   18 m

 For finding the cost of levelling, we need to find the area and then multiply it by the rate for levelling.

Area of the square park   =    Side x Side

                                              =    18 x 18

                                              =  324 sq. m

Cost of levelling 1 sq. m     =   4

Cost of levelling  324 sq.m = 4 x 324

                                               =  1296



6)  

 Find the cost of levelling a square park of side 16 m at 8 per sq.m.

Answer: 2048


SOLUTION 1 :

Given   :

The side of the square park   =   16 m

 For finding the cost of levelling, we need to find the area and then multiply it by the rate for levelling.

Area of the square park   =    Side x Side

                                              =    16 x 16

                                              =  256 sq. m

Cost of levelling 1 sq. m     =   8

Cost of levelling  256 sq.m = 8 x 256

                                               =  2048



7)  

 Find the cost of levelling a square park of side 12 m at 5 per sq.m.

Answer: 720


SOLUTION 1 :

Given   :

The side of the square park   =   12 m

 For finding the cost of levelling, we need to find the area and then multiply it by the rate for levelling.

Area of the square park   =    Side x Side

                                              =    12 x 12

                                              =  144 sq. m

Cost of levelling 1 sq. m     =   5

Cost of levelling  144 sq.m = 5 x 144

                                               =  720



8)  

 Find the cost of levelling a square park of side 17 m at 5 per sq.m.

Answer: 1445


SOLUTION 1 :

Given   :

The side of the square park   =   17 m

 For finding the cost of levelling, we need to find the area and then multiply it by the rate for levelling.

Area of the square park   =    Side x Side

                                              =    17 x 17

                                              =  289 sq. m

Cost of levelling 1 sq. m     =   5

Cost of levelling  289 sq.m = 5 x 289

                                               =  1445



9)

Answer: 2400


SOLUTION 1 :

Given   :

The side of the square park   =   20 m

 For finding the cost of levelling, we need to find the area and then multiply it by the rate for levelling.

Area of the square park   =    Side x Side

                                              =    20 x 20

                                              =  400 sq. m

Cost of levelling 1 sq. m     =   6

Cost of levelling  400 sq.m = 6 x 400

                                               =  2400



10)  

 Find the cost of levelling a square park of side 12 m at 6 per sq.m.

Answer: 864


SOLUTION 1 :

Given   :

The side of the square park   =   12 m

 For finding the cost of levelling, we need to find the area and then multiply it by the rate for levelling.

Area of the square park   =    Side x Side

                                              =    12 x 12

                                              =  144 sq. m

Cost of levelling 1 sq. m     =   6

Cost of levelling  144 sq.m = 6 x 144

                                               =  864
