Triangle Area Base and Height Calculator
Calculate triangle area from base and perpendicular height, or solve the reverse problem for base or height from a known area.
Triangle area from base and height
English search intent for this page is the basic base-height triangle area formula, plus quick reverse calculations for missing base or missing height. The height must be perpendicular to the chosen base or its extension.
A is area; b is base; h is perpendicular height.
