Here are the perimeters of the shapes: 1) This shape is a semicircle. Step 1: Identify the given dimensions. The straight side is the diameter (d) of the semicircle, which is 14 cm. Step 2: Calculate the length of the curved part. The curved part is half the circumference of a circle. The formula for the circumference of a circle is C = d. Length of curved part = (1)/(2) d = (1)/(2) × (22)/(7) × 14 cm. Length of curved part $= 11 × 2 cm = 22
