The perimeter of a rectangle is 34 cm and its length is 7 cm more than its width. What is its area in square cm?
Answer and explanation
Correct answer: B. 60
- Step 1: If the width is x, then 2(x + x + 7) = 34, so x = 5 and the length is 12.
- Step 2: Area = 12 x 5 = 60.
Answer
60.
Why not the others: 64 would be the area of a square with the same perimeter.
