Part 1 A rectangle has a length that is 3 times the width.  Write an expression for the width [a]. Write an expression for the length [b]. Part 2 To find the perimeter of a figure, we use P = 2L + 2W or we add up all the sides. Write a simplified expression for the perimeter of this rectangle. Hint: you cannot have x more than once in the expression if it is fully simplified. The perimeter of the rectangle is [c]
