What is the formula for the area of a rectangle?

The formula for the area of a rectangle is given by multiplying the length by the width, which is expressed as A = length × width. This relationship is based on the concept that the area represents the total number of square units that can fit within the boundaries of the rectangle.

To visualize this, if you consider a rectangle with specific measurements for length and width, the area can be understood as the number of unit squares that can completely fill that rectangle. For each unit of length, there are a certain number of units of width, and their product gives the total area.

Hence, using the formula A = length × width allows for an accurate calculation of that two-dimensional space, confirming that this is the correct answer.
