Which formula represents the area of a rectangle?

The formula for the area of a rectangle is determined by multiplying the length of the rectangle by its width. This is because area is a measure of space within a two-dimensional shape, and multiplying these two dimensions yields the total number of square units that can fit within the rectangle.

The length is one side of the rectangle, while the width is another side that forms a right angle with the length. By multiplying these values, you accurately calculate the total area encompassed by the rectangle’s boundaries. This foundational concept is fundamental in geometry and is essential for various practical applications, such as determining the amount of flooring needed for a room or the space available within a play area for children.

In contrast, the other formulas are not suitable for calculating the area of a rectangle. The equations that involve addition or subtraction do not take into account the necessary multiplicative relationship between length and width. The formula that includes the sum of length and width multiplied by two is instead used to calculate the perimeter of the rectangle, not the area. Therefore, the correct understanding of the area formula is vital for accurately performing tasks related to spatial dimensions.
