**Steve**, Tuesday, October 29, 2013 at 8:10pmw + (5w+1) = 49

now get w and figure length.

**Miah**, Tuesday, October 29, 2013 at 8:16pmSo is it 5w^2+1w=49? I'm still confused.

**Steve**, Tuesday, October 29, 2013 at 8:21pmwho told you to multiply? We don't care about the area. Just add them up. The width plus the length (5w+1) = 1/2 the perimeter

w+5w+1 = 49

6w = 48

w = 8

so, length = 41

**Miah**, Tuesday, October 29, 2013 at 8:23pmMy bad. I forgot that we were adding, not multiplying. Thank you
