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

• A. w + h
• B. w × h
• C. 2 × (w + h)
• D. (w + h) ÷ 2

Answer: (B)

The formula for calculating the area of a rectangle is based on multiplying its width (w) by its height (h). When you multiply these two dimensions, you effectively cover the entire surface inside the rectangle, which gives you the area. This is represented as w × h, where each side contributes to the total space. In contrast, adding the width and height (as indicated in different choices) does not give a measurement of area; it results in a perimeter or a sum of sides, which is the total distance around the rectangle. Similarly, using the formula 2 × (w + h) calculates the perimeter of the rectangle, not its area, as it accounts for all sides rather than the specific measurement of space contained within. Finally, (w + h) ÷ 2 would provide an average of the width and height, which is not relevant for area calculation. Thus, the correct approach to finding the area of a rectangle remains w × h.
