Question

the length and breadth of a rectangular field are in the ratio 3 :2 .If the perimeter of the field is250 m , find the cost of reaping the field at Rupees50 per50m​

Answer 1

Let length = 3x

breadth= 2x

Perimeter = 250m

2(l+b)= 250

2(3x+2x)= 250

5x =125

X = 25

So

length= 3×25 = 75m

breadth= 2×25=50m

Cost of reaping = Rs1 per m

So

Area = l×b = 75×50. 3750 m^2

Cost = Rs 3750
