A wall in Marcus's bedroom is 825

825

feet high and 1623

1623

feet long. If he paints 12

12

of the wall blue, how many square feet will be blue?

If you would like to know how many square feet of the wall will be blue, you can calculate this using the following steps:

8 2/5 feet high * 16 2/3 feet long = 8 2/5 * 16 2/3 = 42/5 * 50/3 = 140 square feet

1/2 * 140 = 140/2 = 70 square feet

The correct result would be 70 square feet.
