    C 18 metres Correct Answer Incorrect Answer
    D 32 metres Correct Answer Incorrect Answer
    E 6 metres Correct Answer Incorrect Answer

    Solution

    Using formula, Area = lb & Area = a2 = (Diagonal2)/2 Area of the rectangular garden = 16 × 8 = 128 m2 = Area of the square garden Therefore, Side of the square garden = √128 m2 Therefore, diagonal of the square garden = √2 x side ⇒ √2 x √128 = √256 ⇒ 16 m
