Question

A square garden has 49 square feet. So the perimeter of the garden must be----feet.

Answer 1

28

Explanation:

If the area of the garden is 49 ft^2 and all sides are equal because it's a square, we can take the square root of 49 to get a side length.

The square root of 49 ft^2 is 7 ft.

Since there are 4 sides to a square, we multiply the length of one side by the number of sides to get the total perimeter.

4 x 7 ft = 28 feet total

Answer 2

The side length of a square is the square root of the area:

Side length = √49 = 7 feet.

The perimeter of a square is 4s = 4*7 = 28 feet.
