Calculate the height of an obtuse triangle whose base is X cm and the area is Y square cm.
- Y * 2 / X
- Y + X / 2
- Y * 2 * X
Explanation from PART66Online
The area of a triangle is half the base times the height: Y = (1/2) * X * h. Rearranging for the height gives h = 2Y / X, which matches Y * 2 / X. This holds for an obtuse triangle too, provided the height is measured perpendicular to the chosen base.
