1)  

 A field is in the form of a rhombus. The diagonals of the fields are 16 m and 17m. Find the cost of levelling it at the rate of   9 per sq.m.

  Answer: 1224


SOLUTION 1 :

Given  :

   d1  =  16 cm

   d2 =  17 cm

Area  =   12 x  d1 x d2

           =   12 x  16 x 17

            =  136.0 cm2

Cost of levelling 1 sq .m    =    9

Cost of levelling  136.0 sq. m =    9 x 136.0

                                                   =    1224

 



2)  

 A field is in the form of a rhombus. The diagonals of the fields are 10 m and 17m. Find the cost of levelling it at the rate of   2 per sq.m.

  Answer: 170


SOLUTION 1 :

Given  :

   d1  =  10 cm

   d2 =  17 cm

Area  =   12 x  d1 x d2

           =   12 x  10 x 17

            =  85.0 cm2

Cost of levelling 1 sq .m    =    2

Cost of levelling  85.0 sq. m =    2 x 85.0

                                                   =    170

 



3)  

 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   9 per sq.m.

  Answer: 1147.5


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    =    9

Cost of levelling  127.5 sq. m =    9 x 127.5

                                                   =    1147.5

 



4)

  Answer: 270


SOLUTION 1 :

Given  :

   d1  =  15 cm

   d2 =  18 cm

Area  =   12 x  d1 x d2

           =   12 x  15 x 18

            =  135.0 cm2

Cost of levelling 1 sq .m    =    2

Cost of levelling  135.0 sq. m =    2 x 135.0

                                                   =    270

 



5)  

 A field is in the form of a rhombus. The diagonals of the fields are 17 m and 15m. Find the cost of levelling it at the rate of   2 per sq.m.

  Answer: 255


SOLUTION 1 :

Given  :

   d1  =  17 cm

   d2 =  15 cm

Area  =   12 x  d1 x d2

           =   12 x  17 x 15

            =  127.5 cm2

Cost of levelling 1 sq .m    =    2

Cost of levelling  127.5 sq. m =    2 x 127.5

                                                   =    255

 



6)  

 A field is in the form of a rhombus. The diagonals of the fields are 20 m and 20m. Find the cost of levelling it at the rate of   2 per sq.m.

  Answer: 400


SOLUTION 1 :

Given  :

   d1  =  20 cm

   d2 =  20 cm

Area  =   12 x  d1 x d2

           =   12 x  20 x 20

            =  200.0 cm2

Cost of levelling 1 sq .m    =    2

Cost of levelling  200.0 sq. m =    2 x 200.0

                                                   =    400

 



7)  

 A field is in the form of a rhombus. The diagonals of the fields are 12 m and 21m. Find the cost of levelling it at the rate of   5 per sq.m.

  Answer: 630

   d1  =  12 cm

   d2 =  21 cm

Area  =   12 x  d1 x d2

           =   12 x  12 x 21

            =  126.0 cm2

Cost of levelling 1 sq .m    =    5

Cost of levelling  126.0 sq. m =    5 x 126.0

                                                   =    630

 



8)

   d2 =  24 cm

Area  =   12 x  d1 x d2

           =   12 x  18 x 24

            =  216.0 cm2

Cost of levelling 1 sq .m    =    6

Cost of levelling  216.0 sq. m =    6 x 216.0

                                                   =    1296

 



9)

   d2 =  16 cm

Area  =   12 x  d1 x d2

           =   12 x  11 x 16

            =  88.0 cm2

Cost of levelling 1 sq .m    =    9

Cost of levelling  88.0 sq. m =    9 x 88.0

                                                   =    792

 



10)  

 A field is in the form of a rhombus. The diagonals of the fields are 20 m and 16m. Find the cost of levelling it at the rate of   5 per sq.m.

  Answer: 800


SOLUTION 1 :

Given  :

   d1  =  20 cm

   d2 =  16 cm
