Question

The perimeter of a rectangle if the width is w centimeters and the length is 12cm less than twice the width

Answer 1

6w - 24 cm = perimeter

Explanation:

width = w cm

length = 2w - 12 cm

perimeter = all sides added together

[w] + [w] + [2w - 12] + [2w - 12]

(combine like terms)

6w - 24 cm = perimeter
