    – 10 cm and its perimeter is 116 cm then find its area?
    A 551 cm² Correct Answer Incorrect Answer
    B 759 cm² Correct Answer Incorrect Answer
    C 936 cm² Correct Answer Incorrect Answer
    D 816 cm² Correct Answer Incorrect Answer
    E 704 cm² Correct Answer Incorrect Answer

    Solution

    Let the length and breadth of rectangle = x and x – 10 cm Perimeter of rectangle = 2 x [Length + Breadth] According to the question Perimeter of rectangle = 116 cm ⇒ 2 x [Length + Breadth] = 116 ⇒ x + x – 10 = 58 ⇒ Length = x = 34 cm Breadth = (x – 10) = 24 cm Area of rectangle = Length x Breadth Area of rectangle = 34 x 24 Area of rectangle = 816 cm²
