Calculate the Area of a Triangle
This will calculate the area of a triangle based on the length of its sides.
Triangle Area - 3′ x 4′ x 5′
| 6 | square feet |
| 864 | square inches |
| 0.66667 | square yards |
| 0.55742 | square meters |
| 5,574.2 | square centimeters |
(results may be rounded)
Area of a Triangle Formula
The area of a triangle, knowing its three sides, is expressed by Heron's formula:
In this formula, a, b, and c represent the lengths of the three sides. s represents the "semiperimeter" or half the perimeter:
