Key Concepts — Quick Reference
This chapter
Area & perimeter of plane figures
| Rectangle | Area = l × b · Perimeter = 2(l + b) |
|---|---|
| Square | Area = a² · Perimeter = 4a |
| Triangle | Area = ½ × base × height |
| Parallelogram | Area = base × height |
| Circle | Area = πr² · Circumference = 2πr (π = 22/7) |
Surface area & volume of solids
| Cuboid | Volume = l × b × h · TSA = 2(lb + bh + hl) |
|---|---|
| Cube | Volume = a³ · TSA = 6a² |
| Cylinder | Volume = πr²h · CSA = 2πrh · TSA = 2πr(r + h) |
