What is the formula for calculating area?

Length + Width
Length * Width
Length / Width
Length - Width

The correct answer is: Length * Width

The formula for calculating area is determined by multiplying the length by the width. This is because area is a measure of the space contained within a two-dimensional shape, typically a rectangle. By multiplying these two dimensions, you obtain the total number of square units that can fit within the shape. This is fundamental in geometry and applies not only to rectangles but also to many other shapes when their dimensions are appropriately defined. For instance, in squares, since all sides are equal, you would also multiply one side by itself. Hence, knowing that area is fundamentally derived from the product of the dimensions reinforces the understanding that length and width interact multiplicatively to define space.
