Write the expression for the perimeter of a rectangle with a length that is 5 inches longer than it’s width

Answer 1

Let P = perimeter and W = width and L = length

There are four sides. Two of them are the Width and 2 are the length. W = W and L = W + 5

So P = W + W + (W + 5) + (W + 5) = 4W + 10

Answer 2

P = 2(w + w + 5)
