Triangle Area Calculator
Triangle Area Calculator
The triangle area calculator computes the area of a triangle given its base and height using the standard half-base-times-height formula.
Conversion Formula
Area = ½ × base × height. The base can be any side; the height must be the perpendicular distance from that base to the opposite vertex.
Step-by-Step Examples
Base: 10, Height: 6 = 30
½ × 10 × 6 = 30 square units.
Base: 7, Height: 4 = 14
½ × 7 × 4 = 14 square units.
Frequently Asked Questions
How do I calculate the area of a triangle?
Multiply the base by the height and divide by 2: A = ½ × b × h.
What is the height of a triangle?
The height (altitude) is the perpendicular distance from the base to the opposite vertex.
Does this work for all triangles?
Yes. The formula A = ½bh works for any triangle as long as the height is measured perpendicular to the base.
What if I only know three sides?
Use Heron's formula: A = √(s(s-a)(s-b)(s-c)) where s = (a+b+c)/2.
What units is the area in?
Area is in square units matching the input. If base and height are in meters, area is in square meters.
