Answer
The perimeter, P, of a rectangle with length l and width w is given by the formula\[P=2l+2w\].
Work Step by Step
The distance measured around the sides of a polygon is called its perimeter. The perimeter is usually measured by finding the sum of the lengths of the sides of the polygon.
For any two-dimensional closed figure, perimeter and area are two important calculations. The area is the computation of entire covered part by the figure. The perimeter is the computation of the length of the boundaries of the given figure.
Hence, in the case of a rectangle, the perimeter can be determined by finding out the sum of all of its sides that is length and width. The opposite sides of a rectangle are equal in length. So, the formula becomes\[2\left( l+w \right)\].
