A square has an area of 49 sq in. How do you find the perimeter?

The perimeter is 28 in.

Step-by-step explanation:

We know that the area is 49 square inches and that the area of a square equals length times width. Also, all sides of a square are equal. 7 times 7 equals 49, so the length and width are both 7 inches. The perimeter is equal to all the sides added together. There are four sides in a square, and we know that each side is 7 inches. Therefore, we can add 7+7+7+7 (or multiply 7 times 4) to get the square's perimeter: 28 inches.
