1)  

 A field is in the form of a rhombus. The diagonals of the fields are 18 m and 18m. Find the cost of levelling it at the rate of   4 per sq.m.

  Answer: 648


SOLUTION 1 :

Given  :

   d1  =  18 cm

   d2 =  18 cm

Area  =   12 x  d1 x d2

           =   12 x  18 x 18

            =  162.0 cm2

Cost of levelling 1 sq .m    =    4

Cost of levelling  162.0 sq. m =    4 x 162.0

                                                   =    648

 



2)  

 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   9 per sq.m.

  Answer: 1287


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    =    9

Cost of levelling  143.0 sq. m =    9 x 143.0

                                                   =    1287

 



3)  

 A field is in the form of a rhombus. The diagonals of the fields are 11 m and 19m. Find the cost of levelling it at the rate of   6 per sq.m.

  Answer: 627


SOLUTION 1 :

Given  :

   d1  =  11 cm

   d2 =  19 cm

Area  =   12 x  d1 x d2

           =   12 x  11 x 19

            =  104.5 cm2

Cost of levelling 1 sq .m    =    6

Cost of levelling  104.5 sq. m =    6 x 104.5

                                                   =    627

 



4)

  Answer: 997.5


SOLUTION 1 :

Given  :

   d1  =  15 cm

   d2 =  19 cm

Area  =   12 x  d1 x d2

           =   12 x  15 x 19

            =  142.5 cm2

Cost of levelling 1 sq .m    =    7

Cost of levelling  142.5 sq. m =    7 x 142.5

                                                   =    997.5

 



5)  

 A field is in the form of a rhombus. The diagonals of the fields are 20 m and 17m. Find the cost of levelling it at the rate of   3 per sq.m.

  Answer: 510


SOLUTION 1 :

Given  :

   d1  =  20 cm

   d2 =  17 cm

Area  =   12 x  d1 x d2

           =   12 x  20 x 17

            =  170.0 cm2

Cost of levelling 1 sq .m    =    3

Cost of levelling  170.0 sq. m =    3 x 170.0

                                                   =    510

 



6)  

 A field is in the form of a rhombus. The diagonals of the fields are 10 m and 15m. Find the cost of levelling it at the rate of   9 per sq.m.

  Answer: 675


SOLUTION 1 :

Given  :

   d1  =  10 cm

   d2 =  15 cm

Area  =   12 x  d1 x d2

           =   12 x  10 x 15

            =  75.0 cm2

Cost of levelling 1 sq .m    =    9

Cost of levelling  75.0 sq. m =    9 x 75.0

                                                   =    675

 



7)  

 A field is in the form of a rhombus. The diagonals of the fields are 14 m and 22m. Find the cost of levelling it at the rate of   6 per sq.m.

  Answer: 924

   d1  =  14 cm

   d2 =  22 cm

Area  =   12 x  d1 x d2

           =   12 x  14 x 22

            =  154.0 cm2

Cost of levelling 1 sq .m    =    6

Cost of levelling  154.0 sq. m =    6 x 154.0

                                                   =    924

 



8)

  Answer: 600


SOLUTION 1 :

Given  :

   d1  =  20 cm

   d2 =  15 cm

Area  =   12 x  d1 x d2

           =   12 x  20 x 15

            =  150.0 cm2

Cost of levelling 1 sq .m    =    4

Cost of levelling  150.0 sq. m =    4 x 150.0

                                                   =    600
