Example 15 Find the perimeter of the given shape (Fig 11.32) (Take Ο = 22/7). Here, Perimeter of given shape = 4 Γ Circumference of semicircle Letβs find circumference of semi-circle Circumference of semicircle Diameter = 14 cm Radius = r = π·πππππ‘ππ/2 = 14/2 = 7 cm Circumference of semicircle = 1/2 Γ Circumference of circle = 1/2 Γ 2πr = πr = 22/7 Γ 7 = 22 cm Now, Perimeter of given shape = 4 Γ Circumference of semicircle = 4 Γ 22 = 88 cm Hence, perimeter of given shape is 88 cm
