      Question

      The perimeter of a rectangle is 60 meters. If the length

      of the rectangle is twice the width, find the area of the rectangle.
      A 200 sq. meters Correct Answer Incorrect Answer
      B 300 sq. meters Correct Answer Incorrect Answer
      C 400 sq. meters Correct Answer Incorrect Answer
      D 500 sq. meters Correct Answer Incorrect Answer

      Solution

      Let the width of the rectangle be x meters. Length = 2x meters. Perimeter of rectangle = 2(length + width) = 60 meters. 2(2x + x) = 60 6x = 60 x = 10. So, the width is 10 meters, and the length is 20 meters. Area = length × width = 20 × 10 = 200 sq. meters. Answer: a) 200 sq. meters
