The formula for the area of a parallelogram
is
We know the base is 10 units long, because the
bottom side extends from 4 units left of the
y-axis to 6 units right of the y-axis. That's
a total of 10 units for the base.
Let's draw the height as a dotted line:
We see that the height extends from 6 units below the x-axis to 5 units
above the x-axis, so that is 11 units.
So
= = 110 square units.
