What This Calculator Solves
Calculate the total area when the hypotenuse and the altitude drawn to the hypotenuse are known.
Finds area by using the hypotenuse as the base of the triangle.
Known values
Hypotenuse c and altitude h
Finds
Area (A)
Main formula
A = (c × h) / 2

Area Formula
A triangle's area is 1/2 × base × height. If you use the hypotenuse (c) as the base, the corresponding height is the altitude to the hypotenuse (h).
Diagram: Altitude to Hypotenuse
The diagram shows the right triangle rotated so the hypotenuse lies flat as the base.
Diagram Key
c = hypotenuse (base)
The long side used as base.
h = altitude (height)
Perpendicular height to hypotenuse.
A = area
Total square units.
A = Area
Computed as (c × h) / 2.
- Altitude h must be less than or equal to c/2.
How to Calculate
- Enter hypotenuse c.
- Enter altitude h.
- Click Calculate.
Worked Example
If hypotenuse is 10 and altitude is 4.8:
The area is 24 square units.
Altitude limits
In any right triangle, the maximum possible altitude to the hypotenuse is exactly half the length of the hypotenuse. If h > c/2, no such right triangle exists.

01 Is this the same area as using the legs? expand_more
Yes. (a × b) / 2 always exactly equals (c × h) / 2.
