Awall in marcus bedroom is 8 1/3 feet high and 16 1/5 feet long if he paints 1/3 of the wall blue how many square feet will be blue

First, we need to find the area of the wall. The formula we use is A=bh. For this problem, b = 16 1/5 ft and h = 8 1/3 ft. Plug the given information into the equation like so:
