CALCULATOR
Perimeter of a Right Triangle Calculator
Find right-triangle boundary from its perpendicular legs. Example: A: 2 m, B: 2 m gives 6.82842712475 m. a,b are perpendicular legs; neither is hypotenuse. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation.
a,b are perpendicular legs; neither is hypotenuse. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation. Derivation: Pythagoras supplies third side; perimeter is sum.
Accepted inputs: A: 0.001 to 1,000 m; B: 0.001 to 1,000 m.
How the calculation works
P = a+b+√(a²+b²)
Worked example
With a 2 m, b 2 m, right-triangle boundary from its perpendicular legs is 6.828427125 m.
Assumptions and limits
a,b are perpendicular legs; neither is hypotenuse. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation. Derivation: Pythagoras supplies third side; perimeter is sum.
