1)  

 A field is in the form of a rhombus. The diagonals of the fields are 12 m and 17m. Find the cost of levelling it at the rate of   7 per sq.m.

  Answer: 714


SOLUTION 1 :

Given  :

   d1  =  12 cm

   d2 =  17 cm

Area  =   12 x  d1 x d2

           =   12 x  12 x 17

            =  102.0 cm2

Cost of levelling 1 sq .m    =    7

Cost of levelling  102.0 sq. m =    7 x 102.0

                                                   =    714

 



2)  

 A field is in the form of a rhombus. The diagonals of the fields are 15 m and 17m. Find the cost of levelling it at the rate of   3 per sq.m.

  Answer: 382.5


SOLUTION 1 :

Given  :

   d1  =  15 cm

   d2 =  17 cm

Area  =   12 x  d1 x d2

           =   12 x  15 x 17

            =  127.5 cm2

Cost of levelling 1 sq .m    =    3

Cost of levelling  127.5 sq. m =    3 x 127.5

                                                   =    382.5

 



3)  

 A field is in the form of a rhombus. The diagonals of the fields are 16 m and 25m. Find the cost of levelling it at the rate of   6 per sq.m.

  Answer: 1200


SOLUTION 1 :

Given  :

   d1  =  16 cm

   d2 =  25 cm

Area  =   12 x  d1 x d2

           =   12 x  16 x 25

            =  200.0 cm2

Cost of levelling 1 sq .m    =    6

Cost of levelling  200.0 sq. m =    6 x 200.0

                                                   =    1200

 



4)  

 A field is in the form of a rhombus. The diagonals of the fields are 13 m and 20m. Find the cost of levelling it at the rate of   4 per sq.m.

  Answer: 520


SOLUTION 1 :

Given  :

   d1  =  13 cm

   d2 =  20 cm

Area  =   12 x  d1 x d2

           =   12 x  13 x 20

            =  130.0 cm2

Cost of levelling 1 sq .m    =    4

Cost of levelling  130.0 sq. m =    4 x 130.0

                                                   =    520

 



5)  

 A field is in the form of a rhombus. The diagonals of the fields are 12 m and 15m. Find the cost of levelling it at the rate of   3 per sq.m.

  Answer: 270


SOLUTION 1 :

Given  :

   d1  =  12 cm

   d2 =  15 cm

Area  =   12 x  d1 x d2

           =   12 x  12 x 15

            =  90.0 cm2

Cost of levelling 1 sq .m    =    3

Cost of levelling  90.0 sq. m =    3 x 90.0

                                                   =    270

 



6)  

 A field is in the form of a rhombus. The diagonals of the fields are 13 m and 18m. Find the cost of levelling it at the rate of   3 per sq.m.

  Answer: 351


SOLUTION 1 :

Given  :

   d1  =  13 cm

   d2 =  18 cm

Area  =   12 x  d1 x d2

           =   12 x  13 x 18

            =  117.0 cm2

Cost of levelling 1 sq .m    =    3

Cost of levelling  117.0 sq. m =    3 x 117.0

                                                   =    351

 



7)  

 A field is in the form of a rhombus. The diagonals of the fields are 12 m and 23m. Find the cost of levelling it at the rate of   2 per sq.m.

  Answer: 276


SOLUTION 1 :

Given  :

   d1  =  12 cm

   d2 =  23 cm

Area  =   12 x  d1 x d2

           =   12 x  12 x 23

            =  138.0 cm2

Cost of levelling 1 sq .m    =    2

Cost of levelling  138.0 sq. m =    2 x 138.0

                                                   =    276

 



8)  

 A field is in the form of a rhombus. The diagonals of the fields are 12 m and 19m. Find the cost of levelling it at the rate of   7 per sq.m.

  Answer: 798


SOLUTION 1 :

Given  :

   d1  =  12 cm

   d2 =  19 cm

Area  =   12 x  d1 x d2

           =   12 x  12 x 19

            =  114.0 cm2

Cost of levelling 1 sq .m    =    7

Cost of levelling  114.0 sq. m =    7 x 114.0

                                                   =    798

 



9)

  Answer: 1080


SOLUTION 1 :

Given  :

   d1  =  18 cm

   d2 =  24 cm

Area  =   12 x  d1 x d2

           =   12 x  18 x 24

            =  216.0 cm2

Cost of levelling 1 sq .m    =    5

Cost of levelling  216.0 sq. m =    5 x 216.0

                                                   =    1080

 



10)  

 A field is in the form of a rhombus. The diagonals of the fields are 13 m and 22m. Find the cost of levelling it at the rate of   6 per sq.m.

  Answer: 858


SOLUTION 1 :

Given  :

   d1  =  13 cm

   d2 =  22 cm

Area  =   12 x  d1 x d2

           =   12 x  13 x 22

            =  143.0 cm2

Cost of levelling 1 sq .m    =    6

Cost of levelling  143.0 sq. m =    6 x 143.0

                                                   =    858
