A rectangle has length 8 cm and width 3 cm. What is its area?

• A. 11 cm^2
• B. 24 cm^2
• C. 24.5 cm^2
• D. 18 cm^2

Answer: (B)

The area of a rectangle is found by multiplying its length by its width. With a length of 8 cm and a width of 3 cm, the area is 8 × 3 = 24 cm^2. The unit cm^2 reflects that you’re measuring area, not length. The other numbers don’t come from multiplying the given dimensions, so they don’t represent the rectangle’s area. Therefore, the area is 24 square centimeters.
