Area Formulas
Common Shapes:
- Rectangle: Area = Length × Width
- Square: Area = Side²
- Circle: Area = π × Radius²
- Triangle: Area = ½ × Base × Height
- Trapezoid: Area = ½ × (Base1 + Base2) × Height
- Ellipse: Area = π × a × b (semi-axes)
- Parallelogram: Area = Base × Height
Perimeter Formulas:
- Rectangle: P = 2(Length + Width)
- Circle: Circumference = 2πr
- Triangle: P = a + b + c (sum of sides)
Unit Conversions:
- 1 square foot = 144 square inches
- 1 square yard = 9 square feet
- 1 square meter = 10.764 square feet
- 1 acre = 43,560 square feet
