  1. Question 1

    Q1. The perimeter of the circular field and the square field is equal. If the area of this square field is 12100m^2, the area of a circular field will be_________?

    • A) 15500 Sq.m
    • B) 15400 Sq.m
    • C) 15200 Sq.m
    • D) 15300 Sq.m

    Answer: 15400 Sq.m

    Explanation: Square area = 12100 m² → side = 110 m → perimeter = 440 m = 2πr → r = 70 m; circle area = (22/7)×70² = 15400 m².
