CALCULATOR
Base of a Triangle Calculator
Find triangle base from area and perpendicular height. Example: Area: 12 m², Height: 2 m gives 12 m. Height is perpendicular to desired base. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation.
Height is perpendicular to desired base. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation. Derivation: Solve A=bh/2 for b.
Accepted inputs: Area: 0.001 to 100,000,000 m²; Height: 0.001 to 1,000 m.
How the calculation works
base = 2 area/height
Worked example
With area 12 m², height 2 m, triangle base from area and perpendicular height is 12 m.
Assumptions and limits
Height is perpendicular to desired base. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation. Derivation: Solve A=bh/2 for b.
