Example 10 Find the perimeter of the given shape (Fig 11.32) (Take Ο = 22/7).Here, Perimeter of given shape = 4 Γ Length of curved blue line = 4 Γ Circumference of half circle Letβs find circumference of half circle Circumference of half circle Diameter = 14 cm Radius = r = π·πππππ‘ππ/2 = 14/2 = 7 cm Circumference of half circle = 1/2 Γ Circumference of circle = π/π Γ 2πr = πr = 22/7 Γ 7 = 22 cm Now, Perimeter of given shape = 4 Γ Circumference of half circle = 4 Γ 22 = 88 cm Hence, perimeter of given shape is 88 cm
