38=2w+2*12

38=2w+24

14=2w

W=7

Heath Ayers · Answer 2

The given equation is:

P = 2w + 2l

We are given that:

P = 38

l = 12

Substitute with these two givens in the above equation to get the value of w which is the only unknown as follows:

P = 2w + 2l

38 = 2w + 2 (12)

38 = 2w + 24

38 - 24 = 2w

2w = 14

w = 14/2 = 7
