Triangle Area Calculator
Calculate triangle area from a base and its perpendicular height.
How to use
- Enter the base length.
- Enter the perpendicular height to that base and calculate.
Capabilities and scope
This applies the direct one-half base-times-height formula.
How it works
It uses A = base × height / 2.
Example
Base 10 and height 6 give area 30.
Useful for
- Find area from drawing dimensions
- Estimate a triangular material or land region
Before you use it
- Height must be perpendicular to the chosen base; a sloping side is not automatically the height.
Frequently asked questions
Does it work for a right triangle?
Yes. The two perpendicular legs can be used as base and height.
