Answer:
The distance is
Step-by-step explanation:
we know that
The formula to calculate the distance between two points is equal to
we have
substitute the values
Check the picture below.
so notice, the sides AB and AC you can pretty much count them off the grid.
now, to get the CB side.

sum all three sides up, and that's the perimeter of the triangle.
