Question

The cost of fencing a square field at Rs 35 per metre is Rs4480. Find the length of each side of the field.​

Answer 1

let the total perimeter of the square = x

Cost of fencing of 1 m = ₹35

Cost of fencing of x meter =

35 × x = 4480

x = 4480/35

x = 128 m

Hence, Perimeter of the square field = 128m

Length of each side = perimeter/4

= 128m/4

= 32m

Hence, the length of each side of the field = 32m
