Answer:
42.
Hope that helps. x
Step-by-step explanation:
(Easy way)
If one side is 12 and the other is 9, we need to do 12 + 12 and 9 + 9 which equals to 42.
(Long way)
With a trapezoid we can get an image of one rectangle and s right-angle triangle next to it. So now we have found out the perimeter of the rectangle and so we're moving on to the triangle. The base is 6 and the height is obviously going to be 12. So what we do is, 12 + 12 = 24 and 6 + 6 = 12 = 36. Since we worked out the perimeter of two rectangles we have to half the number that we got for the triangle rectangle. So half of 36 is 18, and now we add up all the numbers we are left with. 24 + 18 = 42.
