Question

The formula for the perimeter of a rectangle is p=2L + 2W, where L is the length and W is the width of the rectangle. Which is the formula for the length?

Answer 1

P - 2W

L = ------------

2

Explanation:

You are being asked to solve P = 2L + 2W for the length, L.

Let's isolate 2L on the right side by subtracting 2W from both sides:

P - 2W = 2L

Dividing both sides by 2 isolates L:

P - 2W

L = ------------
