    A 416 m² Correct Answer Incorrect Answer
    B 414 m² Correct Answer Incorrect Answer
    C 437 m² Correct Answer Incorrect Answer
    D 228 m² Correct Answer Incorrect Answer

    Solution

    ATQ, Let the length and breadth of the courtyard be ā€˜L’ metres and ā€˜B’ metres, respectively. Perimeter of the courtyard = (924/11) = 84 metres So, 2 Ɨ (L + B) = 84 Or, (L + B) = 42 ATQ; L = B + 4 So, B + 4 + B = 42 Or, 2B = 38 So, B = 19 So, breadth of the courtyard = 19 metres And, length of the courtyard = 19 + 4 = 23 metres So, area of the courtyard = 23 Ɨ 19 = 437 m²
