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:
\(P\): 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 \(P\)
