1)  

 A field is in the form of a rhombus. The diagonals of the fields are 13 m and 24m. Find the cost of levelling it at the rate of   5 per sq.m.

  Answer: 780


SOLUTION 1 :

Given  :

   d1  =  13 cm

   d2 =  24 cm

Area  =   12 x  d1 x d2

           =   12 x  13 x 24

            =  156.0 cm2

Cost of levelling 1 sq .m    =    5

Cost of levelling  156.0 sq. m =    5 x 156.0

                                                   =    780

 



2)  

 A field is in the form of a rhombus. The diagonals of the fields are 15 m and 21m. Find the cost of levelling it at the rate of   8 per sq.m.

  Answer: 1260


SOLUTION 1 :

Given  :

   d1  =  15 cm

   d2 =  21 cm

Area  =   12 x  d1 x d2

           =   12 x  15 x 21

            =  157.5 cm2

Cost of levelling 1 sq .m    =    8

Cost of levelling  157.5 sq. m =    8 x 157.5

                                                   =    1260

 



3)  

 A field is in the form of a rhombus. The diagonals of the fields are 16 m and 16m. Find the cost of levelling it at the rate of   8 per sq.m.

  Answer: 1024


SOLUTION 1 :

Given  :

   d1  =  16 cm

   d2 =  16 cm

Area  =   12 x  d1 x d2

           =   12 x  16 x 16

            =  128.0 cm2

Cost of levelling 1 sq .m    =    8

Cost of levelling  128.0 sq. m =    8 x 128.0

                                                   =    1024

 



4)  

 A field is in the form of a rhombus. The diagonals of the fields are 15 m and 15m. Find the cost of levelling it at the rate of   8 per sq.m.

  Answer: 900


SOLUTION 1 :

Given  :

   d1  =  15 cm

   d2 =  15 cm

Area  =   12 x  d1 x d2

           =   12 x  15 x 15

            =  112.5 cm2

Cost of levelling 1 sq .m    =    8

Cost of levelling  112.5 sq. m =    8 x 112.5

                                                   =    900

 



5)  

 A field is in the form of a rhombus. The diagonals of the fields are 10 m and 22m. Find the cost of levelling it at the rate of   6 per sq.m.

  Answer: 660


SOLUTION 1 :

Given  :

   d1  =  10 cm

   d2 =  22 cm

Area  =   12 x  d1 x d2

           =   12 x  10 x 22

            =  110.0 cm2

Cost of levelling 1 sq .m    =    6

Cost of levelling  110.0 sq. m =    6 x 110.0

                                                   =    660

 



6)  

 A field is in the form of a rhombus. The diagonals of the fields are 15 m and 18m. Find the cost of levelling it at the rate of   7 per sq.m.

  Answer: 945


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    =    7

Cost of levelling  135.0 sq. m =    7 x 135.0

                                                   =    945

 



7)  

 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   7 per sq.m.

  Answer: 1134


SOLUTION 1 :

   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    =    7

Cost of levelling  162.0 sq. m =    7 x 162.0

                                                   =    1134

 



8)
