I will need to find the Area of each of the shapes first

`\begin{gathered} AreaforA=LXB=5*10=50in^2 \\ \text{Area for B = L x B = 7 }*10=70in^2 \\ \text{Area for C = L x B = 5}*10=50in^2 \\ \text{Area for D = L x B = 7 }*10=70in^2 \\ \text{Area for E = L x B = 7 }*5=35in^2 \\ \text{Area for F = L x B = 5}*7=35in^2 \\ \text{Total Area = 50 + 70 +50 +70 + 35 + 35} \\ \text{Total Area = 310in}^2 \\ I\text{ will have to convert this answer to f}eet. \\ 1\text{ inches = }0.0833333foot \\ 1inches^2\text{ =}0.0069444foot^2 \\ 310ches^2\text{ = x} \\ x\text{ = 310 }*\text{ 0.0069444}fo \\ x=2.1526foot^2 \end{gathered}`
