Question

The perimeter of a square needs to be more than 28 inches. Create an inequality to find what the lengths of the sides should be. Solve the inequality by showing all of your work and explaining each step. Explain your answer.

Answer 1

First a square has 4 equal sides
label one side x
so the perimeter of the square must be 4x
4x must be greater than 28
therefore
4x>28
which simplifies to
x>7
All the sides must be greater than 7
