Question

George wants to build a square fence using 80 meters of wire. What is the area of the fence if you use all of the wire equally among each side?

Answer 1

If George is enclosing a square area with 80 meters of wire --

80/4 = 20 on each side

20 * 20 = 400 square meters in area.

Answer 2

Recall that the perimeter of a square is equal to
P = 4*s
where s = length of one side
Therefore,
80 = 4*s
s = 80/4
s = 20 meters
We need to find the area. Recall that the area of a square is just
A = s^2
Substituting,
A = 20^2
A = 400 m^2
