1)  

 A field is in the form of a rhombus. The diagonals of the fields are 11 m and 25m. Find the cost of levelling it at the rate of   8 per sq.m.

  Answer: 1100


SOLUTION 1 :

Given  :

   d1  =  11 cm

   d2 =  25 cm

Area  =   12 x  d1 x d2

           =   12 x  11 x 25

            =  137.5 cm2

Cost of levelling 1 sq .m    =    8

Cost of levelling  137.5 sq. m =    8 x 137.5

                                                   =    1100

 



2)  

 A field is in the form of a rhombus. The diagonals of the fields are 12 m and 15m. Find the cost of levelling it at the rate of   3 per sq.m.

  Answer: 270


SOLUTION 1 :

Given  :

   d1  =  12 cm

   d2 =  15 cm

Area  =   12 x  d1 x d2

           =   12 x  12 x 15

            =  90.0 cm2

Cost of levelling 1 sq .m    =    3

Cost of levelling  90.0 sq. m =    3 x 90.0

                                                   =    270

 



3)  

 A field is in the form of a rhombus. The diagonals of the fields are 11 m and 23m. Find the cost of levelling it at the rate of   6 per sq.m.

  Answer: 759


SOLUTION 1 :

Given  :

   d1  =  11 cm

   d2 =  23 cm

Area  =   12 x  d1 x d2

           =   12 x  11 x 23

            =  126.5 cm2

Cost of levelling 1 sq .m    =    6

Cost of levelling  126.5 sq. m =    6 x 126.5

                                                   =    759

 



4)

  Answer: 1575


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    =    7

Cost of levelling  225.0 sq. m =    7 x 225.0

                                                   =    1575

 



5)  

 A field is in the form of a rhombus. The diagonals of the fields are 13 m and 23m. Find the cost of levelling it at the rate of   8 per sq.m.

  Answer: 1196


SOLUTION 1 :

Given  :

   d1  =  13 cm

   d2 =  23 cm

Area  =   12 x  d1 x d2

           =   12 x  13 x 23

            =  149.5 cm2

Cost of levelling 1 sq .m    =    8

Cost of levelling  149.5 sq. m =    8 x 149.5

                                                   =    1196

 



6)  

 A field is in the form of a rhombus. The diagonals of the fields are 16 m and 24m. Find the cost of levelling it at the rate of   4 per sq.m.

  Answer: 768


SOLUTION 1 :

Given  :

   d1  =  16 cm

   d2 =  24 cm

Area  =   12 x  d1 x d2

           =   12 x  16 x 24

            =  192.0 cm2

Cost of levelling 1 sq .m    =    4

Cost of levelling  192.0 sq. m =    4 x 192.0

                                                   =    768

 



7)  

 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   8 per sq.m.

  Answer: 1344


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    =    8

Cost of levelling  168.0 sq. m =    8 x 168.0

                                                   =    1344

 



8)  

 A field is in the form of a rhombus. The diagonals of the fields are 12 m and 22m. Find the cost of levelling it at the rate of   7 per sq.m.

  Answer: 924


SOLUTION 1 :

Given  :

   d1  =  12 cm

   d2 =  22 cm

Area  =   12 x  d1 x d2

           =   12 x  12 x 22

            =  132.0 cm2

Cost of levelling 1 sq .m    =    7

Cost of levelling  132.0 sq. m =    7 x 132.0

                                                   =    924

 



9)

  Answer: 675


SOLUTION 1 :

Given  :

   d1  =  18 cm

   d2 =  15 cm

Area  =   12 x  d1 x d2

           =   12 x  18 x 15

            =  135.0 cm2

Cost of levelling 1 sq .m    =    5

Cost of levelling  135.0 sq. m =    5 x 135.0

                                                   =    675

 



10)  

 A field is in the form of a rhombus. The diagonals of the fields are 14 m and 20m. Find the cost of levelling it at the rate of   5 per sq.m.

  Answer: 700


SOLUTION 1 :

Given  :

   d1  =  14 cm

   d2 =  20 cm

Area  =   12 x  d1 x d2

           =   12 x  14 x 20

            =  140.0 cm2

Cost of levelling 1 sq .m    =    5

Cost of levelling  140.0 sq. m =    5 x 140.0

                                                   =    700
