what is the area of a triangle?
explain answer as well

Area of triangle = 12 units²

Explanation:

Area of triangle is calculated using the following rule:

Area = 0.5 * base * height

Now, in the given figure each square represents one unit, therefore, we will get the lengths by counting squares

Base = BC = 8 units

Height is the perpendicular distance from vertex A to the base BC = 3 units

Substitute with these values in the above equation to get the area as follows:

Area = 0.5 * 8 * 3 = 12 units²
