Question

The formula p=2/+2w means that the perimeter of a rectangle is equal to twice the sum of its length and its with

Answer 1

w = (P - 2l) / 2

I = (P - 2w) / 2

Step-by-step explanation:

I think they changed the variable format for this question. Both answers are correct.

Answer 2

P = 2l + 2w

solve for w

re-write

2l + 2w = P

subtract 2l from both sides

2w = P - 2l

divide both sides by 2

w = (P - 2l) / 2

Answer is B

w = (P - 2l) / 2
