1. Yes. They are congruent because they are literally the same rectangle.
2. Angles h and g are both 90 degrees because they are rectangles and the inside angles of a rectangle must add up to 360. So you get 90 + 90 + 90 + h = 360. 270 + h = 360. h = 90. Same with g.
Because they are congruent as told in the problem, c = 13 ft. and d = 18 ft.
