If the perimeter of a square is 36in, what is the length of one side?
If the perimeter of a square is 36in, what is the length of one side?
To find the perimeter of a square, we will use the following formula:
where a is the length of any side of the square. Because a square has 4 equal sides, we can use any side in the formula. To find the length of any side, we will solve for a.
Now, we know the perimeter of the square is 36in. So, we will substitute.
Therefore, the length of one side of the square is 9in.
