Area Formulas for Common Shapes

Area is the amount of 2D space a shape occupies, measured in square units (cm2, m2, ft2, in2). Below are the formulas for the most common shapes.

Shape Formulas

ShapeFormula
SquareA = side2
RectangleA = length x width
TriangleA = 0.5 x base x height
CircleA = pi x r2
ParallelogramA = base x height
TrapezoidA = 0.5 x (a + b) x height
EllipseA = pi x a x b

Practical Applications

  • Flooring: Calculate how many square meters of tile, laminate, or carpet you need.
  • Painting: Find the wall area to estimate paint quantity.
  • Gardening: Measure lawn or garden bed area for fertilizer and seeds.
  • Construction: Calculate land, roof, or floor areas.

Unit Conversions

  • 1 m2 = 10.764 ft2
  • 1 hectare = 10,000 m2
  • 1 acre = 4,047 m2
  • 1 km2 = 1,000,000 m2

Frequently Asked Questions

Area of a circle = π × r², where r is the radius. For a circle with radius 5, area = π × 25 ≈ 78.54 square units.
Area = (1/2) × base × height. If you know all three sides, use Heron's formula: s = (a+b+c)/2, Area = √(s(s-a)(s-b)(s-c)).
This calculator works with any unit — just be consistent. If you enter lengths in meters, you get area in square meters. In feet, you get square feet, etc.
