View Questions of Area
Quantitative Aptitude - Area
1. Fundamental Formulas
- Square: \( a^2 \); Rectangle: \( ab \)
- Triangle: \( \frac{1}{2}bh \); Parallelogram: \( bh \)
- Circle: \( \pi r^2 \); Sector: \( \frac{\theta}{360} \pi r^2 \)
2. Composite Figures
- Break into basic shapes and sum their areas.
3. Quick Tips
- Memorize area formulas with units (cm², m²).
- Use approximations: \( \pi ≈ 22/7 \) for exam calculations.
4. Mistakes to Avoid
- Confusing perimeter and area units.
- Using wrong dimensions (height vs slant).
5. Revision Checklist
- Practice composite area scenarios under time limit.
Summary: Use correct formula, break shapes into components, watch units, and approximate intelligently with π.
