Mikey works in a square shaped office. The area of his office is 110.25 square feet. What is the length of one side of Mickey's office?

A square has 4 sides, and they are all equal. Therefore, when finding the area of a square, it is multiplying the same number by itself. This is the same as multiplying one side to the 2nd power. Therefore, you must undo it. You find the square root of 110.25, and you get:

10.5

A=sxs (area of a square)

Therefore s=sqroot of A=sqroot of 110.25

Therefore s=10.5
