Area of a Rectangle

w: width
l: length

The area of a rectangle is given by:

A = w ∙ l

Example: Determine the area of a room that is 5 meters in length and 3 meters in width.

Since a typical room is in the shape of a rectangle, its area can be determined by using the formula given above:

A = w ∙ l = 3 ∙5 = 15 m2
