A wall in Marcus's bedroom is $\displaystyle{8}\frac{{2}}{{5}}\usepackage{cmbright}\Huge\$ feet high and $\displaystyle{16}\frac{{2}}{{3}}\usepackage{cmbright}\Huge\$ feet long. If he paints $\displaystyle\frac{{1}}{{2}}\usepackage{cmbright}\Huge\$ of the wall blue, how many square feet will be blue?
