    The ratio of the breadth to the length of a rectangular

    field is 3:4. The total cost of cutting the grass of the field at the rate of Rs 12 per m2 is Rs. 36864. Find the cost of fencing the boundary of the field at the rate of Rs.13 per m.
    A Rs. 1650 Correct Answer Incorrect Answer
    B Rs. 2912 Correct Answer Incorrect Answer
    C Rs. 3240 Correct Answer Incorrect Answer
    D Rs. 3332 Correct Answer Incorrect Answer

    Solution

    Let the length and breadth of the field is 3x and 4x respectively. Area of the field = 36864/12 = 3072 m2 So, (3x ├Ч 4x) = 3072 тЗТ x2 = 256 тЗТ x = 16 Therefore, the length of the field = 3x = 48 m And the breadth of the field = 4x = 64 m Required cost = 2 ├Ч (48 + 64) ├Ч 13 = Rs. 2912
