A triangle has a base of 4 inches and a height of 10 inches. What is its area, in square inches?
A 24
B 40
C 14
D 20
Correct answer: D — 20
- Area of a triangle = ½ × base × height.
- ½ × 4 × 10 = 20 square inches.
- Why the other options are wrong:
- A (24): This is the correct answer (20) plus 4: an extra 4 was added at the end of the calculation (an off-by-4 error).
- B (40): A triangle is HALF the rectangle: remember the ½.
- C (14): Area multiplies, not adds.
Break a shape into pieces you know (rectangles, triangles, circles), find each area, then add or subtract.
