Question

What is the side length of this square if the perimeter is 28 units and the area is 49 square units?

Answer 1

7

Explanation:

a square's sides are all the same length.

since the area of the square is 49 square ints,

√(49)=7.

You can check this by doing 7(4)=28, since the perimeter is 28 units, and a square has 4 sides.
