The shaded part is AXY, so if you cut the rectangle into smaller parts you will see that AXY takes up 1/8 of the ABCD
89 - 12 could be it. Then u would get 77. So 77 is the number of maps that Marisa gave to the visitors.

When we do this, the base of the parallelogram has length b 1 + b 2, and the height is the same as the trapezoids, so the area of the parallelogram is (b 1 + b 2)*h. Since the two trapezoids of the same size created this parallelogram, the area of one of those trapezoids is one half the area of the parallelogram
