Question

Pre-Algebra Question is an image Below. and Please do Part b also because people don't usually do it

Answer 1

A.) w=P/2-l

Explanation:

Part A.)

P=2(l+w)

P/2= l+w

P/2-l= w

w=P/2-l

Part B.) In order to get (l+w) by itself, so I could subtract l, I had to divide both sides by two. Then I was able to subtract l from both sides to get just w on the right.
