the perimeter of a rectangle is twice the sum of its length and its width. the perimeter is 40 meters and its lenth is 2 meters more then twice its width. what is the length?

math 
Henry,
P = 2(L + W) = 40m,
P = 2L + 2W = 40,
L = (2W + 2)m,
P = 2(2W + 2) + 2W = 40,
4W + 4 + 2W = 40,
6W = 36,
W = 6m.
L = 2W + 2 = 2*6 + 2 = 14m.
