A rectangle is a two-dimensional shape with two sets of equal, parallel sides. These dimensions are the length (L) and the width (W). The formula for the rectangle's area is the product of the two dimensions. The formula for perimeter is

P = 2L + 2W

Since

A = LW = 64

W = 64/L

Substituting to the formula for perimeter would be,

P = 2L + 2 (64/L)

P = 2L + 128/L
