Perimeter of a square is 16 cm. Find the area of this square.

Solution:

• Step 1: Find the side length of the square. The perimeter of a square is calculated by the formula P = 4a, where P is the perimeter and a is the side length. Given that the perimeter is 16 cm, we have:
• 16 cm = 4a
• a = 16 cm / 4
• a = 4 cm
• Step 2: Calculate the area of the square. The area of a square is calculated by the formula A = a², where A is the area and a is the side length. Using the side length we found:
• A = (4 cm)²
• A = 16 cm²

Answer: 16 cm²
