Question

The length of a rectangle is 5/2 units greater than twice its width. If it’s width is w, which expression gives the perimeter of the rectangle in terms of w?

Answer 1

P = 2(L + W)
L = 2W + 5/2

P = 2(2W + 5/2 + W)
P = 2(3W + 5/2)
P = 6W + 5
P - 5 = 6W
(P - 5) / 6 = W or 1/6P - 5/6 = W <===
