What is the formula for the area of a rectangle?

• A. Area = length + width
• B. Area = length × height
• C. Area = length × width
• D. Area = width × height

Answer: (C)

The formula for the area of a rectangle is derived from the understanding that area measures the amount of space inside a two-dimensional shape. For a rectangle, you can visualize it as being made up of squares. The area is calculated by multiplying the length by the width. In this case, the length refers to one side of the rectangle, and the width refers to the side perpendicular to it. When you multiply these two dimensions together, you get the total number of square units that fit within the rectangle, which is what area represents. This formula, Area = length × width, provides a straightforward way to find the area of any rectangle as long as you have the measurements of its length and width. Knowing how to apply this formula is essential in various real-world contexts, such as determining the amount of flooring needed for a room or calculating the surface area for painting a wall.
