The 2

A rectagle has 4 sides. There are 2 lengths and 2 widths.

The would be written like this to start with

P = L + L + W + W

P = 2L + 2W Using the distributive property 2 can be taken outside the brackets

P = (2L + 2W)

P = 2 (L + W) You have shown how the 4 sides can be written more efficiently.

The answer is D <<< Answer
