1)  

 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   9 per sq.m.

  Answer: 945


SOLUTION 1 :

Given  :

   d1  =  14 cm

   d2 =  15 cm

Area  =   12 x  d1 x d2

           =   12 x  14 x 15

            =  105.0 cm2

Cost of levelling 1 sq .m    =    9

Cost of levelling  105.0 sq. m =    9 x 105.0

                                                   =    945

 



2)  

 A field is in the form of a rhombus. The diagonals of the fields are 10 m and 17m. Find the cost of levelling it at the rate of   7 per sq.m.

  Answer: 595


SOLUTION 1 :

Given  :

   d1  =  10 cm

   d2 =  17 cm

Area  =   12 x  d1 x d2

           =   12 x  10 x 17

            =  85.0 cm2

Cost of levelling 1 sq .m    =    7

Cost of levelling  85.0 sq. m =    7 x 85.0

                                                   =    595

 



3)  

 A field is in the form of a rhombus. The diagonals of the fields are 17 m and 18m. Find the cost of levelling it at the rate of   3 per sq.m.

  Answer: 459


SOLUTION 1 :

Given  :

   d1  =  17 cm

   d2 =  18 cm

Area  =   12 x  d1 x d2

           =   12 x  17 x 18

            =  153.0 cm2

Cost of levelling 1 sq .m    =    3

Cost of levelling  153.0 sq. m =    3 x 153.0

                                                   =    459

 



4)  

 A field is in the form of a rhombus. The diagonals of the fields are 14 m and 23m. Find the cost of levelling it at the rate of   5 per sq.m.

  Answer: 805


SOLUTION 1 :

Given  :

   d1  =  14 cm

   d2 =  23 cm

Area  =   12 x  d1 x d2

           =   12 x  14 x 23

            =  161.0 cm2

Cost of levelling 1 sq .m    =    5

Cost of levelling  161.0 sq. m =    5 x 161.0

                                                   =    805

 



5)  

 A field is in the form of a rhombus. The diagonals of the fields are 11 m and 21m. Find the cost of levelling it at the rate of   7 per sq.m.

  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

 



6)  

 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   4 per sq.m.

  Answer: 396


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    =    4

Cost of levelling  99.0 sq. m =    4 x 99.0

                                                   =    396

 



7)  

 A field is in the form of a rhombus. The diagonals of the fields are 15 m and 24m. Find the cost of levelling it at the rate of   3 per sq.m.

  Answer: 540


SOLUTION 1 :

Given  :

   d1  =  15 cm

   d2 =  24 cm

Area  =   12 x  d1 x d2

           =   12 x  15 x 24

            =  180.0 cm2

Cost of levelling 1 sq .m    =    3

Cost of levelling  180.0 sq. m =    3 x 180.0

                                                   =    540

 



8)

  Answer: 300


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    =    4

Cost of levelling  75.0 sq. m =    4 x 75.0

                                                   =    300

   d2 =  24 cm

Area  =   12 x  d1 x d2

           =   12 x  17 x 24

            =  204.0 cm2

Cost of levelling 1 sq .m    =    9

Cost of levelling  204.0 sq. m =    9 x 204.0

                                                   =    1836

 



10)  

 A field is in the form of a rhombus. The diagonals of the fields are 10 m and 24m. Find the cost of levelling it at the rate of   9 per sq.m.

  Answer: 1080


SOLUTION 1 :

Given  :

   d1  =  10 cm

   d2 =  24 cm

Area  =   12 x  d1 x d2
