Find the area of a triangle with a base of 5 cm and a height of 8/9 cm.

Solution to the problem: S is the area of the triangle. We need to find the area, for this we use the formula:
S = 1/2 * a * h, where a = the length of the side (base), h – the height dropped on it
We are given: a = 5cm, h = 8 / 9cm.
S = 1/2 * 5 * 8/9 = 20/9 = 2.22 cm
The answer to the problem: the area of the triangle is 2.22 cm2.
