1)  

 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   8 per sq.m.

  Answer: 1020


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    =    8

Cost of levelling  127.5 sq. m =    8 x 127.5

                                                   =    1020

 



2)  

 A field is in the form of a rhombus. The diagonals of the fields are 19 m and 25m. Find the cost of levelling it at the rate of   3 per sq.m.

  Answer: 712.5


SOLUTION 1 :

Given  :

   d1  =  19 cm

   d2 =  25 cm

Area  =   12 x  d1 x d2

           =   12 x  19 x 25

            =  237.5 cm2

Cost of levelling 1 sq .m    =    3

Cost of levelling  237.5 sq. m =    3 x 237.5

                                                   =    712.5

 



3)  

 A field is in the form of a rhombus. The diagonals of the fields are 14 m and 18m. Find the cost of levelling it at the rate of   3 per sq.m.

  Answer: 378


SOLUTION 1 :

Given  :

   d1  =  14 cm

   d2 =  18 cm

Area  =   12 x  d1 x d2

           =   12 x  14 x 18

            =  126.0 cm2

Cost of levelling 1 sq .m    =    3

Cost of levelling  126.0 sq. m =    3 x 126.0

                                                   =    378

 



4)

  Answer: 540


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    =    4

Cost of levelling  135.0 sq. m =    4 x 135.0

                                                   =    540

 



5)

  Answer: 612


SOLUTION 1 :

Given  :

   d1  =  17 cm

   d2 =  24 cm

Area  =   12 x  d1 x d2

           =   12 x  17 x 24

            =  204.0 cm2

Cost of levelling 1 sq .m    =    3

Cost of levelling  204.0 sq. m =    3 x 204.0

                                                   =    612

 



6)  

 A field is in the form of a rhombus. The diagonals of the fields are 14 m and 21m. Find the cost of levelling it at the rate of   2 per sq.m.

  Answer: 294


SOLUTION 1 :

Given  :

   d1  =  14 cm

   d2 =  21 cm

Area  =   12 x  d1 x d2

           =   12 x  14 x 21

            =  147.0 cm2

Cost of levelling 1 sq .m    =    2

Cost of levelling  147.0 sq. m =    2 x 147.0

                                                   =    294

 



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   2 per sq.m.

   d2 =  21 cm

Area  =   12 x  d1 x d2

           =   12 x  12 x 21

            =  126.0 cm2

Cost of levelling 1 sq .m    =    2

Cost of levelling  126.0 sq. m =    2 x 126.0

                                                   =    252

 



8)
