A rectangle's length is three times its width. If the perimeter is 64, what is the area of the rectangle?
Category: Math · Difficulty: expert
Hint: Express the dimensions in terms of the width.
Answer
384
Explanation
Let width be w, then length is 3w. The perimeter is 2(l + w) = 64, leading to 2(3w + w) = 64, thus 8w = 64, giving w = 8. Area = 3w * w = 24 * 8 = 192.
