What is the area of a square with a perimeter of 28?

Answer 1

78

Answer 2

Squares have 4 equal sides. So lets set x equal to one of the sides of the square.

x = one side of the square

The perimeter of a square is the distance around the outside. This is equal to the sum of the lengths of the sides. Because a square has 4 sides the perimeter is as follows

4x = perimeter

Solving for x in this case gives you 7.

The area of any rectangle is equal to the base * height. In a square this means side * side or side2.

area = x2

Solving for the area in the case given we find that the area of a square with a perimeter of 28 is equal to 49 units2

Answer 3

49

Answer 4

7
