Did we solve your problem today?

Find a triangle's area using the simplest formula: half base times height.

The math behind it

Area = ½ × base × height, where height is measured perpendicular to the base.

Worked example

Base 10, height 6 → ½ × 10 × 6 = 30.

FAQ

What if I only know the three sides?

Use Heron's formula: s = (a+b+c)/2, area = √(s(s−a)(s−b)(s−c)).
