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

• A. 24
• B. 21
• C. 18
• D. 32

Answer: (A)

The area of a rectangle comes from multiplying its length by its width. With length 8 and width 3, the calculation is 8 × 3 = 24, so the area is 24 square units. The other numbers come from different pairings that don’t match the given dimensions: 21 could be 7 × 3, 18 could be 6 × 3 or 9 × 2, and 32 could be 8 × 4. Since the sides are fixed at 8 and 3, only 8 × 3 gives the correct area of 24.
