Question

the length and breadth of a rectangular field are in the ratio 3:2. If the perimeter of the field is 250 m, find the cost of the reparing the field at rupees 15 per 50msq

Answer 1

let the length and breadth of the field be 3 X and 2x respectively

according to question
2 (3 x + 2 x )= 250
5x=250/2=125
x=125÷5=25

so the length and breadth are....
3x=75 m
2x=50 m

area=75×50=3,750 m sq.

cost=15×3750/50= 1,125 rs
