A = (1/2)bh
b is the baseh is the height of the triangle
For example, if we had an isosceles triangle with a base of 8 centimeters and a height of 10 centimeters, we would plug b = 8 and h = 10 into the formula to find the area, like this:
A = (1/2)bh
A = (1/2) ⋅ 8 ⋅ 10
A = 40
We see that the area of an isosceles triangle with base 8 centimeters and height 10 centimeters is 40 square centimeters.
