Question

a farmer is buying fencing to surround a square field of area 3600m^2. What length of fencing does he need to buy?

Answer 1

240 m

Explanation:

The area of a square field is 3600 m².

We need to find the length of fencing he needs to buy. It means we need to find the perimeter of the field.

The area of a square field is given by :

A = side²

So,

`s=√(3600) \ m\\\\s=60\ m`

Length of fencing = perimeter

= 4(s)

= 4(60)

= 240 m

So, he would need to buy 240 m of fencing.
