How is the area of a rectangle calculated?

• A. Length plus width
• B. Length divided by width
• C. Length multiplied by width
• D. Length minus width

Answer: (C)

To calculate the area of a rectangle, the formula used is length multiplied by width. This approach stems from the fundamental idea of area in geometry, which refers to the amount of space contained within a shape. In the case of a rectangle, one can visualize the length and the width as forming a grid of unit squares. Each square represents a unit of area. By multiplying the length by the width, you essentially count how many of these unit squares can fit inside the rectangle. For example, if a rectangle has a length of 5 units and a width of 3 units, the area would be 5 multiplied by 3, yielding a total area of 15 square units. This method is applicable to all rectangles regardless of their size, making it a reliable and straightforward way to determine the area of this shape.
