Find the perimeter of the following trapezoid:
Use the formula for 
triangles in order to find the lengths of all the sides and bases.
The formula is:
Where 
is the length of the side opposite the 
.
Beginning with the 
side, if we were to create a 
triangle, the length of the base is 
, and the height is 
.
Creating another triangle on the left, we find the height is , the length of the base is 
, and the side is 
.
