1)  

 A field is in the form of a rhombus. The diagonals of the fields are 19 m and 21m. Find the cost of levelling it at the rate of   2 per sq.m.

  Answer: 399


SOLUTION 1 :

Given  :

   d1  =  19 cm

   d2 =  21 cm

Area  =   12 x  d1 x d2

           =   12 x  19 x 21

            =  199.5 cm2

Cost of levelling 1 sq .m    =    2

Cost of levelling  199.5 sq. m =    2 x 199.5

                                                   =    399

 



2)  

 A field is in the form of a rhombus. The diagonals of the fields are 16 m and 20m. Find the cost of levelling it at the rate of   4 per sq.m.

  Answer: 640


SOLUTION 1 :

Given  :

   d1  =  16 cm

   d2 =  20 cm

Area  =   12 x  d1 x d2

           =   12 x  16 x 20

            =  160.0 cm2

Cost of levelling 1 sq .m    =    4

Cost of levelling  160.0 sq. m =    4 x 160.0

                                                   =    640

 



3)  

 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   6 per sq.m.

  Answer: 828


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    =    6

Cost of levelling  138.0 sq. m =    6 x 138.0

                                                   =    828

 



4)  

 A field is in the form of a rhombus. The diagonals of the fields are 11 m and 18m. Find the cost of levelling it at the rate of   2 per sq.m.

  Answer: 198


SOLUTION 1 :

Given  :

   d1  =  11 cm

   d2 =  18 cm

Area  =   12 x  d1 x d2

           =   12 x  11 x 18

            =  99.0 cm2

Cost of levelling 1 sq .m    =    2

Cost of levelling  99.0 sq. m =    2 x 99.0

                                                   =    198

 



5)  

 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

 



6)  

 A field is in the form of a rhombus. The diagonals of the fields are 17 m and 17m. Find the cost of levelling it at the rate of   5 per sq.m.

  Answer: 722.5


SOLUTION 1 :

Given  :

   d1  =  17 cm

   d2 =  17 cm

Area  =   12 x  d1 x d2

           =   12 x  17 x 17

            =  144.5 cm2

Cost of levelling 1 sq .m    =    5

Cost of levelling  144.5 sq. m =    5 x 144.5

                                                   =    722.5

 



7)  

 A field is in the form of a rhombus. The diagonals of the fields are 20 m and 22m. Find the cost of levelling it at the rate of   4 per sq.m.

  Answer: 880


SOLUTION 1 :

Given  :

   d1  =  20 cm

   d2 =  22 cm

Area  =   12 x  d1 x d2

           =   12 x  20 x 22

            =  220.0 cm2

Cost of levelling 1 sq .m    =    4

Cost of levelling  220.0 sq. m =    4 x 220.0

                                                   =    880

 



8)  

 A field is in the form of a rhombus. The diagonals of the fields are 18 m and 24m. Find the cost of levelling it at the rate of   7 per sq.m.

  Answer: 1512


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    =    7

Cost of levelling  216.0 sq. m =    7 x 216.0

                                                   =    1512

 



9)

  Answer: 576


SOLUTION 1 :

Given  :

   d1  =  16 cm

   d2 =  24 cm

Area  =   12 x  d1 x d2

           =   12 x  16 x 24

            =  192.0 cm2

Cost of levelling 1 sq .m    =    3

Cost of levelling  192.0 sq. m =    3 x 192.0

                                                   =    576

 



10)  

 A field is in the form of a rhombus. The diagonals of the fields are 10 m and 21m. Find the cost of levelling it at the rate of   9 per sq.m.

  Answer: 945


SOLUTION 1 :
