The formula A =.5 can be used to find the area of a triangle where b is the base and h is the height.
To find the area of a triangle using the formula A = 0.5 * b * h, you would first measure the base (b) of the triangle and the height (h) from the base to the highest point of the triangle.
Then, you would substitute these values into the formula and multiply them together. Finally, you would multiply the result by 0.5 to find the area of the triangle.
For example, if the base of a triangle is 6 units and the height is 4 units, the area of the triangle would be:
A = 0.5 * 6 * 4
A = 0.5 * 24
A = 12 square units
Therefore, the area of the triangle with a base of 6 units and a height of 4 units is 12 square units.
