Question

The measure of one side of a square (s+3) inches long.which pair of expressions both represent the perimeter of this square??

Answer 1

Perimeter = 2w + 2l

Since its a square, the length and width are equal therefore:

2(s + 3) + 2(s + 3) = Perimeter

You can simplify this into a variety of ways:

1. 4(s + 3)
2. 2s + 6 + 2s + 6
3. 4s + 12
