Question: 374
2. The length of a rectangle is four times its width. If the perimeter of the rectangle is 50, what is the area of the rectangle?
- A. 5
- B. 10
- C. 20
- D. 50
Correct Answer: E
Explanation:
E
Let x represent the width of the rectangle, and write an equation to solve for x based on the given perimeter: x + x + 4x + 4x = 50. Combine like terms and divide both sides by 10: x = 5. Thus, the width is 5, and the length is 20. The area is 100.
