How is the area of a rectangle calculated?

• A. Length plus width
• B. Length times width
• C. 2 times the length plus width
• D. Length divided by width

Answer: (B)

The area of a rectangle is calculated by multiplying its length by its width. This is because the area represents the total number of square units that can fit inside the rectangle. When you think of a rectangle, its length is one side and the width is the perpendicular side. By multiplying these two dimensions together, you determine how many unit squares can fill the entire rectangle. For instance, if a rectangle has a length of 5 units and a width of 3 units, the area would be calculated as follows: Area = Length × Width = 5 × 3 = 15 square units. This fundamental formula is essential in geometry and is applied in various real-world contexts, such as determining the amount of flooring needed for a room or the area of a garden. Understanding this concept allows students to solve problems related to area effectively.
