2.) (3 pts) Let R be the region in the first quadrant bounded only by the lines y = 0, x + y = 10 and the curve y = 13. After sketching the region, determine its type (either dyd or dady, but not both). Use this information to set up and calculate a double integral for the area of R. As this problem asks for area, you will be integrating the function (constant) 1 over R.
