Question

What is the length of a rectangle who’s permitter is P if the width is 6

Answer 1

(P-12)/2 = L

Explanation:

1. Start off with an equation in terms of perimeter

P = (2)(6) + (2)(L)

2. Multiply the two and the six

P = 12+ (2)(L)

3. Move the terms around so only "L" is on one side

(P-12)/2 = L
