Calculates area from a base and perpendicular height.

Open in editor
LaTeXA=bh

Variables

  • b: base
  • h: perpendicular height

How to use this formula

Calculates area from a base and perpendicular height.

Important notes

  • The slanted side is not the height unless perpendicular.

Quick example

b=8,h=3 gives A=24.

Applicability, worked calculation, and verification

Assumptions and domain checks

  • The slanted side is not the height unless perpendicular.
  • Use one consistent unit system and confirm whether lengths, areas, volumes, and angles use the dimensions implied by the formula.

Worked example

Input

Output

b=8,h=3 gives A=24.

Common mistakes

  • Before substituting values into Parallelogram Area, map each variable to its definition and preserve every sign, exponent, subscript, and grouping mark.
  • For the Parallelogram Area, do not report a length, area, or volume with the wrong unit dimension, and keep intermediate precision until the final rounding step.
