What is the formula for the area of a rectangle?

The area of a rectangle is calculated using the formula that involves multiplying the length and the width of the rectangle. In this context, length (l) and width (w) are the two dimensions that define the rectangle's size.

When you multiply these two dimensions together (A = lw), you obtain the area, which quantifies the amount of space covered by the rectangle. This relationship highlights how increasing either the length or the width will result in a larger area.

The other formulations presented in the choices involve different geometric shapes or methods of calculating area. For instance, the formula for a triangle's area is represented as A = bh, where b is the base and h is the height. Meanwhile, A = s² denotes the area of a square, where s is the length of a side. These formulas emphasize the importance of understanding the specific characteristics of different shapes in geometry.
