What is the correct formula for finding the area of a rectangle?

Length x Width
Length + Width
2(Length + Width)
Length - Width

The correct answer is: Length x Width

The formula for finding the area of a rectangle is determined by multiplying its length by its width. This relationship arises from the definition of area as the amount of space contained within a shape. In the case of a rectangle, the length represents one side of the rectangle, while the width represents the adjacent side. When you multiply these two dimensions together, you effectively calculate how many square units can fit within the rectangle. For example, if the length is 5 units and the width is 3 units, the area would be 5 x 3 = 15 square units. The other options provided—adding the length and width, calculating the perimeter, or subtracting one from the other—do not yield the area of a rectangle. Thus, the multiplication of length by width is the correct method to derive the area, making it the appropriate choice.
