Questions & Answers
Q: What is the difference between perimeter and area?
Perimeter refers to the total length of the boundary of a closed figure, while area refers to the region occupied by the closed figure. Perimeter is a measure of distance, while area is a measure of space.
Q: How do you calculate the perimeter of a rectangle?
To find the perimeter of a rectangle, you add up the lengths of all four sides. If the length of one side is "l" and the length of the other side is "b," then the perimeter is equal to 2 times (l + b).
Q: What are the properties of a rectangle?
In a rectangle, the opposite sides are equal in length and parallel. All four angles are also equal to 90 degrees.
Q: How do you calculate the perimeter of a square?
To find the perimeter of a square, you add up the lengths of all four equal sides. If the length of one side is "l," then the perimeter is equal to 4 times "l."
