Question

I have a square piece of paper that I need to paint.The paper has an area of 64 square inches.What is the length of the paper?

Answer 1

If the piece of paper is a square, then both sides need to be the same length. The area of a square is equal to the following...

Area of Square = Side Length * Side Length

If the area is 64, then the side length would be the sqrt(64) which = 8 inches.

Answer 2

First, it is important to understand that a square has all 4 sides that are the same length.

The area of a square is l x w, which is basically the length to the power of two since the length and width have the same measures.

Equation:

L^2 = Area

Plug in the known numbers:

L^2 = 64



Now, find the square root on both sides of the equation:
√L^2 = √64
L = 8


Therefore, the length of the paper is 8 inches long.
