Area of a triangle
(b•h)/2 EX: (7•6)/2 = 21
The area of a triangle can be calculated using the formula A=1/2bh, where A is the area of the triangle, b is the base of the triangle, and h is the height of the triangle. To use this formula, you need to know the values of b and h.
To find the base of a triangle, you need to look for the longest side of the triangle. The height is the perpendicular distance from the base to the opposite vertex of the triangle. If you are given the length of the base and the height, you can simply substitute the values in the formula and calculate the area of the triangle.
Example: Given a triangle with a base of 6cm and a height of 4cm, what is the area of the triangle?
Solution:
Using the formula,
A = 1/2 * b * h
A = 1/2 * 6cm * 4cm
A = 12cm²
Therefore, the area of the triangle is 12cm².
