A parallelogram has base 9 and height 5. What is its area?

• A. 35
• B. 50
• C. 55
• D. 45

Answer: (D)

For a parallelogram, the area is found by multiplying the base by the height, where the height is the perpendicular distance between the bases. With a base of 9 and a height of 5, the area is 9 × 5 = 45. The number 45 matches this calculation, so it’s the correct result. The other numbers would come from different base-height combinations (for example, 7 × 5 = 35, 10 × 5 = 50, 11 × 5 = 55), which don’t fit the given base and height.
