COUNT
to find the needed lengths.
In this example, the base of the triangle
lies on the grid of the graph paper, and the altitude also
lies on the grid of the graph paper.
To COUNT: stand
at A and take one step to the right to the next grid line.
Continue stepping and counting until you reach C. From
counting, we know the base
is 6 and the altitude is 3.
The area of a triangle formula:
