Question 145317: Find an algebraic expression for the perimeter of a rectangle, given that the length is x yards and the width is 10 yards shorter Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! Perimeter = 2W + 2x
W = Width
x = Length (I would have used L)
W = x-10
So, P = 2(x-10)+2x
P = 2x-20 + 2x
P = 4x-20
