Question
A square has the same perimeter as a rectangle with
length 18 cm and breadth 10 cm. Find the circumference of a semicircle whose radius is the same as the side of the square.Solution
Perimeter of the rectangle = 2(18 + 10) = 2 × 28 = 56 cm Perimeter of the square = 4 × side of square 56 = 4 × side of square Side of square = 14 cm Radius of the semicircle = 14 cm Circumference of the semicircle = πr + 2r = 22/7 × 14 + 2 × 14 = 44 + 28 = 72 cm
