Calculate area of different shapes including rectangle, square, circle, triangle, and trapezoid.
Area = Length × Width
Area = Length × Width
Example: 5 × 3 = 15 square units
Area = Side²
Example: 4² = 16 square units
Area = πr²
Example: π × 3² ≈ 28.27 square units
Area = ½ × Base × Height
Example: ½ × 6 × 4 = 12 square units
Area = ½ × (Base₁ + Base₂) × Height
Example: ½ × (5 + 3) × 4 = 16 square units
