Worked Solution

Step 1: Find the perimeter of the rectangle. Perimeter = 2 × (length + width) = 2 × (10 + 6) = 2 × 16 = 32 cm Step 2: The square has the same perimeter, so the square's perimeter = 32 cm. Step 3: A square has 4 equal sides, so each side = 32 ÷ 4 = 8 cm. Step 4: Area of square = side × side = 8 × 8 = 64 cm² Answer: 64 cm²

Correct answer: 64 cm²
