1)  

 A field is in the form of a rhombus. The diagonals of the fields are 19 m and 16m. Find the cost of levelling it at the rate of   5 per sq.m.

  Answer: 760


SOLUTION 1 :

Given  :

   d1  =  19 cm

   d2 =  16 cm

Area  =   12 x  d1 x d2

           =   12 x  19 x 16

            =  152.0 cm2

Cost of levelling 1 sq .m    =    5

Cost of levelling  152.0 sq. m =    5 x 152.0

                                                   =    760

 



2)  

 A field is in the form of a rhombus. The diagonals of the fields are 18 m and 22m. Find the cost of levelling it at the rate of   2 per sq.m.

  Answer: 396


SOLUTION 1 :

Given  :

   d1  =  18 cm

   d2 =  22 cm

Area  =   12 x  d1 x d2

           =   12 x  18 x 22

            =  198.0 cm2

Cost of levelling 1 sq .m    =    2

Cost of levelling  198.0 sq. m =    2 x 198.0

                                                   =    396

 



3)  

 A field is in the form of a rhombus. The diagonals of the fields are 15 m and 23m. Find the cost of levelling it at the rate of   6 per sq.m.

  Answer: 1035


SOLUTION 1 :

Given  :

   d1  =  15 cm

   d2 =  23 cm

Area  =   12 x  d1 x d2

           =   12 x  15 x 23

            =  172.5 cm2

Cost of levelling 1 sq .m    =    6

Cost of levelling  172.5 sq. m =    6 x 172.5

                                                   =    1035

 



4)

  Answer: 1122


SOLUTION 1 :

Given  :

   d1  =  17 cm

   d2 =  22 cm

Area  =   12 x  d1 x d2

           =   12 x  17 x 22

            =  187.0 cm2

Cost of levelling 1 sq .m    =    6

Cost of levelling  187.0 sq. m =    6 x 187.0

                                                   =    1122

 



5)

  Answer: 1152


SOLUTION 1 :

Given  :

   d1  =  12 cm

   d2 =  24 cm

Area  =   12 x  d1 x d2

           =   12 x  12 x 24

            =  144.0 cm2

Cost of levelling 1 sq .m    =    8

Cost of levelling  144.0 sq. m =    8 x 144.0

                                                   =    1152

 



6)  

 A field is in the form of a rhombus. The diagonals of the fields are 14 m and 24m. Find the cost of levelling it at the rate of   6 per sq.m.

  Answer: 1008


SOLUTION 1 :

Given  :

   d1  =  14 cm

   d2 =  24 cm

Area  =   12 x  d1 x d2

           =   12 x  14 x 24

            =  168.0 cm2

Cost of levelling 1 sq .m    =    6

Cost of levelling  168.0 sq. m =    6 x 168.0

                                                   =    1008

 



7)  

 A field is in the form of a rhombus. The diagonals of the fields are 12 m and 24m. Find the cost of levelling it at the rate of   5 per sq.m.

  Answer: 720


SOLUTION 1 :

Given  :

   d2 =  24 cm

Area  =   12 x  d1 x d2

           =   12 x  12 x 24

            =  144.0 cm2

Cost of levelling 1 sq .m    =    5

Cost of levelling  144.0 sq. m =    5 x 144.0

                                                   =    720

 



8)  

 A field is in the form of a rhombus. The diagonals of the fields are 10 m and 16m. Find the cost of levelling it at the rate of   9 per sq.m.

  Answer: 720


SOLUTION 1 :

Given  :

   d1  =  10 cm

   d2 =  16 cm

Area  =   12 x  d1 x d2

           =   12 x  10 x 16

            =  80.0 cm2

Cost of levelling 1 sq .m    =    9

Cost of levelling  80.0 sq. m =    9 x 80.0

                                                   =    720

 



9)

   d2 =  16 cm

Area  =   12 x  d1 x d2

           =   12 x  16 x 16

            =  128.0 cm2

Cost of levelling 1 sq .m    =    5

Cost of levelling  128.0 sq. m =    5 x 128.0

                                                   =    640

 



10)  

 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   4 per sq.m.

  Answer: 950


SOLUTION 1 :

Given  :

   d1  =  19 cm

   d2 =  25 cm
