The measure of one side of a square is (s + 3) inches long. Which pair of expressions

both represent the perimeter of this square?

4 (s + 3) or 4s + 12 represents the perimeter of this square

Solution:

Given that measure of one side of a square is (s + 3) inches long

To find: expression that represent the perimeter of this square

To find the perimeter of a square, just add up all the lengths of the sides

The perimeter of square is given as:

Perimeter of square = 4a

Where "a" is the length of side

Given measure of one side of a square is (s + 3) inches long

Since the length of sides of square equal,

Perimeter of square = 4a = 4 (s + 3)

Perimeter of square = 4 (s + 3)

The expression that represent the perimeter of this square is:

Perimeter of square = 4 (s + 3) or 4s + 12
