1)  

 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   3 per sq.m.

  Answer: 660


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    =    3

Cost of levelling  220.0 sq. m =    3 x 220.0

                                                   =    660

 



2)  

 A field is in the form of a rhombus. The diagonals of the fields are 10 m and 25m. Find the cost of levelling it at the rate of   7 per sq.m.

  Answer: 875


SOLUTION 1 :

Given  :

   d1  =  10 cm

   d2 =  25 cm

Area  =   12 x  d1 x d2

           =   12 x  10 x 25

            =  125.0 cm2

Cost of levelling 1 sq .m    =    7

Cost of levelling  125.0 sq. m =    7 x 125.0

                                                   =    875

 



3)  

 A field is in the form of a rhombus. The diagonals of the fields are 20 m and 18m. Find the cost of levelling it at the rate of   4 per sq.m.

  Answer: 720


SOLUTION 1 :

Given  :

   d1  =  20 cm

   d2 =  18 cm

Area  =   12 x  d1 x d2

           =   12 x  20 x 18

            =  180.0 cm2

Cost of levelling 1 sq .m    =    4

Cost of levelling  180.0 sq. m =    4 x 180.0

                                                   =    720

 



4)

  Answer: 808.5


SOLUTION 1 :

Given  :

   d1  =  11 cm

   d2 =  21 cm

Area  =   12 x  d1 x d2

           =   12 x  11 x 21

            =  115.5 cm2

Cost of levelling 1 sq .m    =    7

Cost of levelling  115.5 sq. m =    7 x 115.5

                                                   =    808.5

 



5)

  Answer: 1035


SOLUTION 1 :

Given  :

   d1  =  10 cm

   d2 =  23 cm

Area  =   12 x  d1 x d2

           =   12 x  10 x 23

            =  115.0 cm2

Cost of levelling 1 sq .m    =    9

Cost of levelling  115.0 sq. m =    9 x 115.0

                                                   =    1035

 



6)  

 A field is in the form of a rhombus. The diagonals of the fields are 18 m and 25m. Find the cost of levelling it at the rate of   5 per sq.m.

  Answer: 1125


SOLUTION 1 :

Given  :

   d1  =  18 cm

   d2 =  25 cm

Area  =   12 x  d1 x d2

           =   12 x  18 x 25

            =  225.0 cm2

Cost of levelling 1 sq .m    =    5

Cost of levelling  225.0 sq. m =    5 x 225.0

                                                   =    1125

 



7)  

 A field is in the form of a rhombus. The diagonals of the fields are 14 m and 15m. Find the cost of levelling it at the rate of   3 per sq.m.

   d2 =  15 cm

Area  =   12 x  d1 x d2

           =   12 x  14 x 15

            =  105.0 cm2

Cost of levelling 1 sq .m    =    3

Cost of levelling  105.0 sq. m =    3 x 105.0

                                                   =    315

 



8)
