1. Formula of area for a triangle: S = 1/2 * ВН * AC.

2. Find AC, for this we subtract the abscissa A from the abscissa.

3. Find ВН, for this we subtract the ordinate H from the ordinate B (since H is on the AC, the ordinates will be equal.

4. Substitute numbers in the formula, count, we get the answer.
