A wall in Marcus's bedroom is 8 2/5 feet high and 18 1/3 feet long. If he paints 1/2 of the wall blue, how many square feet will be blue?

$77 f e e {t}^{2}$

Explanation:

Area of the wall is $8 \frac{2}{5} \times 18 \frac{1}{3}$

$\frac{42}{5} \times \frac{55}{3}$

$\frac{14}{5} \times \frac{55}{1}$

$\frac{14}{1} \times \frac{11}{1} = 154 f e e {t}^{2}$

The area we want is half of this $77 f e e {t}^{2}$
