Height From Area and Base
Math check: height = 2 x area / base
Result
Enter area and base to compute the height.

Formula

h = 2A / b

How to Use It

  1. Enter the triangle area.
  2. Enter the corresponding base length.
  3. Read the perpendicular height from the result panel.

Worked Example

If the area is 24 and the base is 8, then the height is 2 x 24 / 8 = 6.

This is the perpendicular distance from the base to the opposite vertex.

Notes

The base must be non-zero, otherwise the height is undefined.
