Question

The length of a rectangular ground is 4 times
its breadth. If its perimeter is 220 m, find its
dimensions. Also, find the cost of fencing the
ground at the rate of 35 per metre. .
​

Answer 1

Breadth : x
Length : 4x
Perimeter : 220

Perimeter = 2(l+b) = 220
= 2(4x + x) = 220
= 8x + 2x = 220
= 10x = 220
= x= 22


Cost for fencing = 220 * 35
= 7700


Your answer is = length : 88m
Breadth : 22m
Cost for fencing : Rs. 7700
