1)  

 A field is in the form of a rhombus. The diagonals of the fields are 11 m and 16m. Find the cost of levelling it at the rate of   3 per sq.m.

  Answer: 264


SOLUTION 1 :

Given  :

   d1  =  11 cm

   d2 =  16 cm

Area  =   12 x  d1 x d2

           =   12 x  11 x 16

            =  88.0 cm2

Cost of levelling 1 sq .m    =    3

Cost of levelling  88.0 sq. m =    3 x 88.0

                                                   =    264

 



2)  

 A field is in the form of a rhombus. The diagonals of the fields are 18 m and 23m. Find the cost of levelling it at the rate of   8 per sq.m.

  Answer: 1656


SOLUTION 1 :

Given  :

   d1  =  18 cm

   d2 =  23 cm

Area  =   12 x  d1 x d2

           =   12 x  18 x 23

            =  207.0 cm2

Cost of levelling 1 sq .m    =    8

Cost of levelling  207.0 sq. m =    8 x 207.0

                                                   =    1656

 



3)  

 A field is in the form of a rhombus. The diagonals of the fields are 17 m and 22m. Find the cost of levelling it at the rate of   3 per sq.m.

  Answer: 561


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    =    3

Cost of levelling  187.0 sq. m =    3 x 187.0

                                                   =    561

 



4)  

 A field is in the form of a rhombus. The diagonals of the fields are 12 m and 16m. Find the cost of levelling it at the rate of   2 per sq.m.

  Answer: 192


SOLUTION 1 :

Given  :

   d1  =  12 cm

   d2 =  16 cm

Area  =   12 x  d1 x d2

           =   12 x  12 x 16

            =  96.0 cm2

Cost of levelling 1 sq .m    =    2

Cost of levelling  96.0 sq. m =    2 x 96.0

                                                   =    192

 



5)  

 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   2 per sq.m.

  Answer: 336


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    =    2

Cost of levelling  168.0 sq. m =    2 x 168.0

                                                   =    336

 



6)  

 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   6 per sq.m.

  Answer: 675


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    =    6

Cost of levelling  112.5 sq. m =    6 x 112.5

                                                   =    675

 



7)  

 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

 



8)

  Answer: 312


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    =    2

Cost of levelling  156.0 sq. m =    2 x 156.0

                                                   =    312

  Answer: 495


SOLUTION 1 :

Given  :

   d1  =  15 cm

   d2 =  22 cm

Area  =   12 x  d1 x d2

           =   12 x  15 x 22

            =  165.0 cm2

Cost of levelling 1 sq .m    =    3

Cost of levelling  165.0 sq. m =    3 x 165.0

                                                   =    495

 



10)
