Which formula represents the area of a rectangle?

The formula for the area of a rectangle is derived from the definition of area, which is the amount of space contained within the boundaries of a shape. For a rectangle, the area can be calculated by multiplying its length by its breadth (or width).

In a rectangle, each pair of opposite sides are equal in length, and the area can be visualized as the total number of square units that can fit inside the rectangle. When you multiply the length of the rectangle by the breadth, you determine how many unit squares can fit within that rectangle, thus accurately calculating its area.

The other options do not represent the area correctly. Adding the length and breadth gives a perimeter-like result, while multiplying by 2 results in double the perimeter. The subtraction of breadth from length does not reflect any geometric measure relevant to area. Therefore, the correct representation of area for a rectangle is indeed length multiplied by breadth.
