<h3>What is the definition of area of a rectangle?</h3>
The area of a rectangle covers is the space it takes up inside the boundaries of its four sides. The dimensions of a rectangle determine its area. In general, the area of a rectangle is equal to the product of its length and breadth of the rectangle.
The formula of area of rectangle is

let the given page represents a rectangle.
We take the length of the advertisement is
unit and breadth of the advertisement is
unit.
The area of the advertisement 

Therefore, the area covered by the advertisement on the page is
