Area and Perimeter of a Square

Area of a Square and Perimeter

• A square has four equal sides.
• The area of a square is calculated by squaring the length of one side (Area = side × side).
• The perimeter of a square is calculated by multiplying the length of one side by 4 (Perimeter = 4 × side).

Given Information

• The area of the square is 81 sq.m.

Finding the Side Length

• To find the side length, take the square root of the area.
  • √81 sq.m = 9 m
• Therefore, the side length of the square is 9 meters.

Calculating the Perimeter

• Now that we know the side length, we can calculate the perimeter.
  • Perimeter = 4 × side length
  • Perimeter = 4 × 9 m
• The perimeter of the square is 36 meters.
