Find the slope of the line that passes through (4,5) and 1,2

The perimeter of a figure is the distance around the figure.

To find the perimeter of the trapezoid shown, we can simply add all the sides. Since there are no numbers we can count each block as 1 unit.

Let's identify our values:

Top of trapezoid = 1 unit

Bottom of trapezoid = 9 units

Left and right side of trapezoid = 10 units "added together"

Now, we can add these numbers up and we will get the perimeter of the figure.

1 + 9 + 10 = 20

Therefore, the perimeter of the trapezoid is 20 units.
