 2. How is the perimeter of a rectangle calculated?
Ans. The perimeter of a rectangle is calculated by adding the lengths of all four sides. It can also be calculated as twice the sum of the length and width of the rectangle.
 3. What is the formula for finding the perimeter of a triangle?
Ans. The formula for finding the perimeter of a triangle is the sum of the lengths of its three sides. If the triangle has sides of lengths a, b, and c, the perimeter is given by a + b + c.
 4. Can the perimeter of a circle be calculated?
Ans. No, the perimeter of a circle cannot be calculated using a simple formula. Instead, the distance around the outside of a circle is known as its circumference, and it is calculated using the formula 2πr, where r is the radius of the circle.
 5. How can the perimeter of a complex shape be calculated?
Ans. To calculate the perimeter of a complex shape, break it down into simpler shapes whose perimeter can be easily calculated. Add the lengths of all the sides of the simpler shapes to find the total perimeter of the complex shape.
