Question

A square has an area of 100m2. What is the length of each side? please help and explain!!!

Answer 1

The length is 10 meters.

A square has 4 sides that are all the same length. This means that if one side was, say, 20 cm, every side would be 20 cm.

Recall that to solve for area, you simply have to multiply the length by the width. Since a square has all equal sides, the length and the width will be equal.

Since we know that the area is 100 m^2, we can make an equation:
n * n = 100
n = sqrt(100)
n = 10
