- 1
The area of a triangle can be found using the formula: Area = base × height ÷ 2.
- 2
When finding area, the units are always expressed as square units, such as square feet or square meters.
- 3
A triangle is exactly half of a rectangle or parallelogram, which is why we divide the base times height by two to find the area of a triangle.
