Why the answer is B, and why the others tempt you.
**The reasoning** The area of a triangle uses a simple formula: **Area = ½ × base × height** Think of it this way: a triangle is exactly *half* of a rectangle. If you had a rectangle with length 8 cm and width 6 cm, its area would be 8 × 6 = 48 cm². But a triangle with the same base and height takes up only half that space. So: Area = ½ × 8 × 6 = ½ × 48 = **24 cm²** **Why the wrong options tempt you** - **Option A (14 cm²)**: This trap catches students who *add* base and height (8 + 6 = 14) instead of multiplying. Area is never found by addition! - **Option C (48 cm²)**: You forgot to multiply by ½. You calculated the full rectangle instead of half of it. - **Option D (96 cm²)**: You might have doubled instead of halving — maybe you multiplied 48 × 2 by mistake. **Quick takeaway** Triangle area is *always* half the rectangle with the same base and height: **A = ½bh**. Never add dimensions to find area!
