Calculating Area of Shapes

Area is the measure of the two-dimensional space enclosed by a shape. This calculator supports rectangles, circles, triangles, trapezoids, ellipses, and parallelograms β€” covering the most common shapes you'll encounter in geometry, construction, and everyday measurements.

Common Area Formulas

  • Rectangle: Length Γ— Width
  • Circle: Ο€ Γ— radiusΒ²
  • Triangle: Β½ Γ— base Γ— height
  • Trapezoid: Β½ Γ— (parallel side a + parallel side b) Γ— height
  • Ellipse: Ο€ Γ— semi-major axis Γ— semi-minor axis
  • Parallelogram: base Γ— height
