How to find the perimeter of a rectangle?
The perimeter of a rectangle can be calculated by adding the lengths of all four sides of the rectangle.
If the length of the rectangle is denoted by “l” and the width by “w”, then the formula for the perimeter (P) is:
P = 2l + 2w
Alternatively, we can also express this as:
P = 2(l + w)
Therefore, to find the perimeter of a rectangle, we need to know its length and width and then apply the above formula to calculate it.
