Question 1012433: A rectangle of length y cm has a 4 cm width shorter than its length write down the expression for (1) the width of the rectangle
(2) the perimeter of the rectangle Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! The width is 4 cm shorter than length y so we would call that (y - 4) cm.
The perimeter is
P = 2L + 2W = 2y + 2(y - 4) = 2y + 2y - 8 = (4y - 8) cm
