The perimeter of the figure consists of the four semicircular arcs only (the square sides are internal).
• Each semicircle has the same diameter, equal to the side of the square.
• Arc length of one semicircle = \( \pi r = \pi \times \dfrac{d}{2} \).
• Four semicircles = 4 × \( \pi \times \dfrac{d}{2} = 2\pi d \).
• From the figure, diameter = 42 cm.
• Perimeter = \( 2 \times \dfrac{22}{7} \times 42 = 2 \times 22 \times 6 = 264 \) cm.
Final Answer: 264 cm
