Question

The perimeter of a rectangular-shaped garden is 40 meters. Let w represent the width of the garden in meters. What does the expression (20 — w) w represent?
A The perimeter of half of the garden in meters
B The area of half of the garden in square meters
• C The perimeter of the garden in meters
D The area of the garden in square meters

Answer 1

D. Since 2(length + width) = 40, length + width = 20 so length = 20 − w. The expression (20 − w)w = length × width, the area of the garden (square meters).
