I have a figure with the shaded region in the middle
The shaded region is 8 feet with 2 feet high and if I split it because there’s a little notch 2 feet with 1 foot height in an 8 inches width again now I have to find the area outside the width is 16 feet the height is 8 feet and since the shaded region is in the middle the other side of the width is 2 feet help
