Question

The side of a square field is 100 m. Find the length of fence required all around it. If three layers of metal wire has to be used to fence it, what is the length of wire needed?

Answer 1

Length of square field=100m

Perimeter of square field=4×s

4×100=400m

3 layers of metal sheet required.

Friends required to cover the square field=400×3=1200m

Answer 2

The length of wire needed is 1200 m

Step-by-step explanation:

Side of square = 100 m

Perimeter of square = 4 \times Side =$4 \times 100 = 400 m$

Length of fence all around in 1 layer = 400 m

Length of fence all around in 3 layers = $400 \times 3 = 1200 m$

Hence the length of wire needed is 1200 m
