Question

The area of a square is 484 square inches. How long is each side?

Answer 1

Answer:

$\sqrt{484} =22$

Step-by-step explanation:

Answer 2

Each side is 21 square inches.

The formula for area of a square is:

A=a^2

So to find the area from that you would replace the area (484 sq. in) for A and solve.

a^2=484

Square root on both sides and you’re left with.

a=21
