Question: 1 / 400

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

Area = length + width

Area = length - width

Area = length × width

The correct understanding of how to calculate the area of a rectangle involves multiplying its length by its width. The formula, Area = length × width, captures the essential relationship between these two dimensions, where length represents one side of the rectangle and width represents the other.

When you multiply the length and width, you essentially determine the total number of square units that can fit within the boundaries of the rectangle. This is crucial in various practical applications, such as construction, where knowing the area allows one to estimate materials needed for flooring or painting.

The other formulas do not accurately reflect the process of calculating area. Adding, subtracting, or dividing length and width does not convey the concept of how much space is contained within a geometric shape, which is the fundamental objective of area calculation.
