A rectangle's length is twice its width. If the perimeter is 48 units, what are the length and width?
Category: Math · Difficulty: hard
Hint: Use the perimeter formula to find the dimensions.
Answer
Length: 16, Width: 8
Explanation
Let width be w, then length = 2w. The perimeter is 2(length + width) = 48. Solving gives w = 8 and length = 16.
This is a hard math riddle — a tricky one that takes a little thought. The answer is Length: 16, Width: 8.
