Question
A square’s side length is equal to the radius of a
circle, whose area is 2464 m². Determine the perimeter of the square.Solution
ATQ,
Let the radius of the circle be ‘r’ m
π × r² = 2464
(22/7) × r² = 2464
r² = 784
r = 28
Since the side length of the square = radius of the circle = 28 m
Perimeter of the square = 4 × 28 = 112 metres
