Question

P = 2l + 2w

Answer 1

Yes, the perimeter of a rectangle is (2 times the length) multiplied by (2 times the width). What is it you need?

Answer 2

w=P-I OR W=P/2-I OR W=P/2+I

Answer 3

Okay:
p = 2l + 2w

Subtract 2l from both sides.

p - 2l = 2w

Divide both sides by 2.

1/2p - l = w

Answer 4

\[w = \frac{ 1 }{ 2 }p - l\]
