Question

The length and breadth of a rectangular field are in ratio 3:2 the cost of covering the field at Rs6.50per m is Rs 520.Find the dimension of the field

Answer 1

Answer:

Let the length and breath be 3x and 2x respectively.

Perimeter of field=2(l+b)=2(3x+2x)=10x m.

Cost for 1 m =₹6.50

Cost for 10x m=₹6.50×10x

=₹65x

Cost of covering the field=₹520

=>65x=520

=>x=520/65

=>x=8

Length=3×8=24cm

Breadth=2×8=16cm
