Question 56004
The length of the rectangle (l) = 2w+3  (twice the width plus 3 in)
The width of the rectangle (w) = w

l = 2w+3
w = w

P = 2l + 2w
36 = 2(2w+3) + 2w ++++++ distribute the 2
36 = 4w + 6 + 2w +++++++ combine like terms
36 = 6w + 6 ++++++++++++ subtract 6 from each side
30 = 6w ++++++++++++++++ divide each side by 6
5 = w

The width of the rectangle would be 5
The length would be 13
