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

Let’s compose a short condition for the problem in order to solve it:
The base of the triangle is 5 cm;
The height of the triangle is 8/9 cm;
Area of a triangle – ?;
To solve the problem, you need to remember the formula for the area of a triangle.
S = 1/2 * a * h,
where a is the length of the base of the triangle, h is the height of the triangle, lowered to the base;
Since we know both the length of the height and the length of the base of the triangle, we can find its area:
S = 1/2 * 5 * 8/9 = 40/18 = 20/9 = 2 whole 2/9 cm² – area;
Answer: 2 whole 2/9 cm².
