    perimeter is 104 m. Find how much percent less the breadth of the field is compared to the length of the field?
    A 55% Correct Answer Incorrect Answer
    B 65% Correct Answer Incorrect Answer
    C 70% Correct Answer Incorrect Answer
    D Can't be determined Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    Given: Area = 800 m² Perimeter = 104 m Let length = L, breadth = B 2(L + B) = 104 → L + B = 52 → L = 52 − B L × B = 800 → (52 − B) × B = 800 → 52B − B² = 800 → B² − 52B + 800 = 0 Discriminant = 52² − 4×800 = 2704 − 3200 = −496 Hence, Can’t be determined — no real solution exists. Given area and perimeter are inconsistent.
