Answer
A rectangle is a closed two-dimensional figure with four sides and all angles are right angles. The perimeter is known as the sum of lengths of all sides.
Work Step by Step
The distance measured around the sides of a closed figure is called its perimeter. The perimeter is usually measured by finding the sum of the lengths of the sides of the polygon.
A rectangle is a closed figure with four sides having opposite sides equal in length and all four angles are right angles.
Hence, the perimeter (P) of a rectangle is the sum of twice of length (l) and twice of its width (w). Computation of the perimeter of the rectangle can be done from the below-mentioned formula:
\[P=2\left( l+w \right)\]
