    perimeter of the rectangle is 60 cm, what is the area?
    A 250 cm² Correct Answer Incorrect Answer
    B 150 cm² Correct Answer Incorrect Answer
    C 200 cm² Correct Answer Incorrect Answer
    D 225 cm² Correct Answer Incorrect Answer

    Solution

    Let the width be w. Then, length l=2w Perimeter 2(l+w) =60   = 2(2w+w) =60 6w=60 w=10 So, length l=20. Area =l×w=20×10=200
