2. How do you calculate the perimeter of a rectangle?
The perimeter of a rectangle is the total length of all its sides. To calculate the perimeter, you add the lengths of all four sides of the rectangle. The formula for the perimeter of a rectangle is: P = 2(L + W), where P is the perimeter, L is the length and W is the width of the rectangle.
3. How do you calculate the area of a rectangle?
To calculate the area of a rectangle, you multiply the length by the width of the rectangle. The formula for the area of a rectangle is: A = L x W, where A is the area, L is the length and W is the width of the rectangle.
4. What is the diagonal of a rectangle?
The diagonal of a rectangle is the line segment that connects opposite corners of the rectangle. It is also the longest straight line that can be drawn within the rectangle. The length of the diagonal of a rectangle can be found using the Pythagorean theorem, given that the length and width of the rectangle are known.
