What is the formula for calculating the area of a rectangle?

1. Length + Width

2. Length X Width

3. 2 (Length + Width)

4. 2 (Length + Height)

The correct answer is: Length X Width

The formula for calculating the area of a rectangle is determined by multiplying its length by its width. This is rooted in the definition of area, which is a measure of the space contained within the boundaries of a two-dimensional shape. In the case of a rectangle, where opposite sides are equal, the area is derived from the product of its two defining dimensions: length and width. Using this formula allows for the accurate calculation of space covered by the rectangle, providing essential information in various practical applications, such as construction, landscaping, and interior design. By learning and applying this straightforward calculation, one can efficiently address real-world scenarios involving rectangular dimensions.
