Calculate The Perimeter Of A Rectangle

Last updated: Saturday, June 24, 2023

The perimeter of a rectangle is the total length of its four sides. It is calculated by adding the length of all four sides of the rectangle, which are typically denoted as L (length) and W (width).

The formula for the perimeter of a rectangle is given as:

Perimeter = 2(L + W)

Rectangles are commonly found in everyday objects, such as doors, windows, and bookshelves. Calculating the perimeter of a rectangle is useful in many real-life situations, such as determining how much fencing is needed for a rectangular yard or how much material is required to create a picture frame.

The formula for determining the perimeter of a rectangle is defined as:
$$P$$ $$=$$ $$2$$ $$\cdot$$ $$(L+W)$$
$$P$$: the perimeter of the rectangle
$$L$$: the lengths of the longer sides
$$W$$: the length of the shorter sides
The SI unit of perimeter is: $$meter\text{ }(m)$$

Find $$P$$
