Then multiply the length and width.

Length x Width = Area.

So, if your room measures 11 feet wide x 15 feet long, your total area will be 165 square feet..

What is the perimeter formula?

The formula for the perimeter of a rectangle is often written as P = 2l + 2w, where l is the length of the rectangle and w is the width of the rectangle. The area of a two-dimensional figure describes the amount of surface the shape covers. You measure area in square units of a fixed size.
