Area Calculator

Calculate the area of common geometric shapes: rectangle, circle, triangle, and trapezoid. Includes automatic conversion between square meters (m²), square feet (ft²), and square varas (traditional Guatemalan unit).

Area Formulas

Rectangle

Rectangle area

A = length × width

Circle

Circle area

A = π × r²

Triangle

Triangle area

A = (base × height) / 2

Trapezoid

Trapezoid area

A = ((base₁ + base₂) / 2) × height

What is a Square Vara?

The vara is a traditional unit of measurement widely used in Guatemala for measuring land and property. One Guatemalan vara equals 0.8359 meters.

Vara conversions
  • 1 square vara = 0.6987 m²
  • 1 m² = 1.4312 square varas
  • 1 manzana = 10,000 square varas = 6,987 m² ≈ 0.7 hectares

Useful Conversions

| From | To | Multiply by | |---|---|---| | m² | ft² | 10.764 | | ft² | m² | 0.0929 | | m² | varas² | 1.4312 | | varas² | m² | 0.6987 |

Common Uses

  • Land and lots: Calculate land area for buying/selling
  • Construction: Estimate materials like flooring, paint, or roofing
  • Agriculture: Measure crop plots
  • Architecture: Floor plans and space design

For irregular land, divide it into regular shapes (rectangles and triangles), calculate each area, and add them together. For better accuracy, use a land survey.

One manzana of land in Guatemala equals 10,000 square varas, which is approximately 6,987 square meters or 0.7 hectares.

A Guatemalan vara measures 0.8359 meters (83.59 centimeters). It is a colonial-era unit still widely used in real estate transactions in Guatemala.

Multiply square meters by 10.764. For example: 50 m² × 10.764 = 538.2 ft².

Area measures the surface (in square units), while perimeter measures the boundary or edge of a shape (in linear units).
