Explanation:

Step1: Recall triangle - area formula

The formula for the area of a triangle is $A=\frac{1}{2}bh$, where $b$ is the base and $h$ is the height.

Step2: Determine base and height from the grid

We need to count the number of grid - units for the base and height of the triangle from the coordinate - plane. Assume we find the base $b$ and height $h$ values by counting the grid squares.

Step3: Calculate the area

Substitute the values of $b$ and $h$ into the formula $A = \frac{1}{2}bh$. Let's say we find $b = 4$ units and $h= 6$ units. Then $A=\frac{1}{2}\times4\times6=12$.
