A square has a perimeter of 40 m. What is its area?

Correct Answer: 100 m²

Step 1: Understand that a square has four equal sides.
Step 2: Know that the perimeter of a square is the total length around it, which is calculated as 4 times the length of one side.
Step 3: Use the formula for perimeter: Perimeter = 4 × Side.
Step 4: Since the perimeter is given as 40 m, set up the equation: 40 m = 4 × Side.
Step 5: To find the length of one side, divide the perimeter by 4: Side = 40 m / 4 = 10 m.
Step 6: Now that you have the length of one side (10 m), you can find the area of the square.
Step 7: Use the formula for area: Area = Side × Side or Area = Side².
Step 8: Calculate the area: Area = (10 m) × (10 m) = 100 m².

Perimeter of a Square – The perimeter of a square is calculated by adding the lengths of all four sides, which is four times the length of one side.
Area of a Square – The area of a square is calculated by squaring the length of one side.
