Question

The cost of putting a fence around a square field at Rs. 35 per metre is Rs. 4480.Find the length of each side of the field​

Answer 1

Answer:

Total cost of fencing = Rs 4480

Rate of fencing = Rs 35/m

Perimeter of the field = $\frac{Total Cost}{Rate}$ = $\frac{Rs .4480}{Rs.35/m}$ = $\frac{4480}{35}$m = 128 m

Let the length of each side of the field be $x$ metres.

Perimeter = (4$x$) metres

∴ 4$x$ = 128

⇒ $x$ = $\frac{128}{4}$ = 32

Hence, the length of each side of the field is 32 m.
