If a rectangle has length 8 and width 3, what is its area?

• A. 11
• B. 6
• C. 28
• D. 24

Answer: (D)

Area is the amount of space inside a rectangle, found by multiplying its length by its width. With length 8 and width 3, the area is 8 × 3 = 24 square units. This matches how many 1-by-1 squares fit inside the rectangle. The other numbers don’t come from multiplying the sides: 11 would be from adding 8 and 3, 6 could be 2 × 3 or 8 − 2, and 28 would require a different multiplication.
