CALCULATOR
Square Feet of a Triangle Calculator
Find triangle area from foot measurements. Example: Base: 2 ft, Perpendicular height: 2 ft gives 2 ft². Perpendicular height, not sloped side. Flat Euclidean shape; stated measurements in displayed units. No waste, thickness, structural suitability or curved-earth claim. Floating point rounding is display only.
Perpendicular height, not sloped side. Flat Euclidean shape; stated measurements in displayed units. No waste, thickness, structural suitability or curved-earth claim. Floating point rounding is display only. Derivation: Area=base×height/2 in coherent foot units.
Accepted inputs: Base: 0.001 to 1,000 ft; Perpendicular height: 0.001 to 1,000 ft.
How the calculation works
area ft² = base ft × perpendicular height ft /2
Worked example
With base 2 ft, perpendicular height 2 ft, triangle area from foot measurements is 2 ft².
Assumptions and limits
Perpendicular height, not sloped side. Flat Euclidean shape; stated measurements in displayed units. No waste, thickness, structural suitability or curved-earth claim. Floating point rounding is display only. Derivation: Area=base×height/2 in coherent foot units.
