Question

the length and breadth of a rectangular field are in the ratio 3 : 2.if the perimeter of the field is 250m, find the cost of reaping the field at ₹15 per 50m2.​

Answer 1

Answer:

Let the length and breadth of the rectangular field be 3x and 2x respectively.

Therefore,2(3x+2x)=250 m.

or,10x=250 m

or, x=25 m

Therefore,

Length=(3*25) m=75 m

Breadth=(2*25) m=50 m

Therefore,

Area of the field=(75*50)m²=3750 m²

Therefore,

Cost of reaping the field at the rate of Rs.15 per 50 m²=Rs.(15/50*3750)=Rs. 1125
