Answer:
Area = 76

Explanation:
you can cut into two rectangles
first one:
top and bottom sides = 4m
two sides = 9m
Area = b*h = 9m * 4m = 36

second one
top and bottom sides = 8m
two sides = 14m - 9m = 5m
Area = b*h = 8m * 5m = 40

Now add both rectangle areas for the total shaded Area = 36 + 40 = 76
