Worked Solution
Step 1: A quarter circle's perimeter = curved arc + 2 straight radii.
Step 2: Curved arc = ¼ × circumference = ¼ × 2πr = ¼ × 2 × 22/7 × 14 = ½ × 22/7 × 14 = 22 cm.
Step 3: Two straight radii = 2 × 14 = 28 cm.
Step 4: Perimeter = 22 + 28 = 50 cm.
Final: 50 cm.
Answer: 50 cm
Correct answer: 50 cm
