A wall is to be painted. A small rectangle in the middle of the wall will remain white to use for a projector. Find the area of the shaded region that will be painted.

The area of the entire wall is ft
The area of the space for the projector is ft
The area of the space to be painted is ft

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
