to solve the perimeter of this trapezoid, we'll first need to calcuate the value of the height. we can do this by using the Pythagorean Theorem.
(19 - 13)^2 + h^2 = 10^2
6^2 + h^2 = 100
36 + h^2 = 100
h^2 = 64
h = 8
so now we can calculate the perimeter.
to do this, we simply just add 13 + 10 + 19 + 8 to get 50, and we're done!
hope this helped! sorry if my explanations weren't too clear. please let me know if you are confused about anything i did
