FAQs on What is Perimeter of a Rectangle? Video Lecture - Class 7

1. What is the formula to calculate the perimeter of a rectangle?

Ans. The formula to calculate the perimeter of a rectangle is: P = 2(l + w) where P represents the perimeter, l represents the length, and w represents the width of the rectangle.

2. How do I find the perimeter of a rectangle if only one side is given?

Ans. If only one side of the rectangle is given, you cannot directly calculate the perimeter. The perimeter is calculated by adding up all the sides of the rectangle. So, you would need to know at least two sides (length and width) to find the perimeter.

3. Can the perimeter of a rectangle be equal to its area?

Ans. No, the perimeter and area of a rectangle are two different measurements. The perimeter is the total distance around the rectangle, while the area is the amount of space inside the rectangle. In general, the perimeter and area of a rectangle are not equal.

4. How can I find the length or width of a rectangle if only the perimeter is given?

Ans. If only the perimeter of a rectangle is given, you cannot determine the length or width of the rectangle uniquely. Multiple combinations of length and width can have the same perimeter. To find the length or width, you would need additional information, such as the ratio of length to width or the area of the rectangle.

5. Can the perimeter of a rectangle be negative?

Ans. No, the perimeter of a rectangle cannot be negative. The perimeter is a measure of distance, and distance cannot be negative. The perimeter is always a positive value representing the total length of all sides of the rectangle.
