Worked Solution

Step 1: Find the perimeter of the rectangle. Perimeter = 2 × (length + width) = 2 × (14 + 6) = 2 × 20 = 40 cm Step 2: Find the side length of the square. A square has 4 equal sides, so side = 40 ÷ 4 = 10 cm Step 3: Find the area of the square. Area = side × side = 10 × 10 = 100 cm² Answer: The area of the square is 100 cm².

Correct answer: 100
