In this example, we are asked to find the perimeter of the trapezoid shown. The perimeter of a figure is the distance around the figure. To find the perimeter of the trapezoid, we can simply just add the lengths of the sides. In this case, we would add 4 + 4 + 6 + 5 = 19 in.
Therefore, the perimeter of the trapezoid is 19 in.
