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
