Question
The side length of a square is equal to the radius of a
circle whose area is 1540 m². Find the perimeter of the square.Solution
ATQ,
Let the radius of the circle be ‘r’ m
π × r² = 1540
(22/7) × r² = 1540
r² = 490
r = 22
Since the side length of the square = radius of the circle = 22 m
Perimeter of the square = 4 × 22 = 88 metres
