how do u calculate the area of a triangle

i know all you do is the base * the height * 1/2
thanks
To calculate the area of a triangle, you can use the formula:
Area = (base * height) / 2
Here's how you can calculate it step-by-step:
1. Measure the length of the base of the triangle.
2. Measure the perpendicular height from the base to the opposite vertex (the highest point of the triangle). If the height is not given, you can use the following method to find it:
a. Draw a line segment perpendicular to the base from the opposite vertex.
b. Measure the length of this line segment.
3. Take the length of the base and multiply it by the height.
4. Divide the result by 2.
For example, let's say the base of the triangle is 5 units and the height is 8 units. Plugging these values into the formula, we get:
Area = (5 * 8) / 2
= 40 / 2
= 20 square units
So, the area of the triangle is 20 square units.
