The formula for calculating the area depends on the shape. For a rectangle, it's length × width. For a circle, it's π × radius^2. For a triangle, it's 0.5 × base × height. Each shape has a specific formula that considers its unique dimensions to determine the space it occupies.

FAQs & Answers

  1. How do you calculate the area of a rectangle? To calculate the area of a rectangle, multiply its length by its width.
  2. What is the formula to find the area of a circle? The area of a circle is found using the formula π times the radius squared (π × radius²).
  3. How is the area of a triangle calculated? The area of a triangle is calculated as 0.5 multiplied by the base and the height (0.5 × base × height).
