A wall 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?

45 ft^2

Step-by-step explanation:

First find the total area of this one wall. It is (8 1/3 ft) (16 1/5 ft), or approx. (8.33 ft) (16.2 ft) = 134.95 ft^2.

One third of that total area comes to 44.98 ft^2, or approx 45 ft^2.
