The perimeter of the shape = Length of the boundary
The perimeter of a semi-circle = \(\frac{\pi~×~D}{2}\)
Calculation:
Given:
D = 70 mm, Length = 70 mm, Breadth = 50 mm
The perimeter of a semi-circle = \(\frac{\pi~×~D}{2}\)
⇒ Perimeter of the semi-circle = \(\frac{\pi~×~70}{2}\) = 110 mm
⇒ Perimeter of the shape = 110 + (70 + 50 + 50) = 280 mm
