Answer 1

$\begin{gathered} 1.)2ft+5in \\ 2.)4ft+11in \\ 3.)2ft+9in \\ \\ \text{Sum the ft:} \\ 2ft+4ft+2ft=8ft \\ \\ \text{Sum the in:} \\ 5in+11in+9in=25in \\ \\ \text{Turn the in into ft:} \\ 1ft=12in \\ \\ \\ \text{For the 25 in you take 24 and turn it into ft;} \\ 24in\cdot\frac{1ft}{12in}=2ft \\ \\ \text{Then, you have:} \\ 25in=2ft+1in \\ \\ \text{The total height is:} \\ 8ft+2ft+1in=10ft+1in \\ \end{gathered}$

Then, the total height is 10 feet and 1 inch
