we separate the figure
find the area of each shape
[tex]\begin{gathered} A=w\times l \\ A=2\times5 \\ A=10 \end{gathered}[/tex]First area is 10 square ft
[tex]\begin{gathered} A=w\times h \\ A=6\times2 \\ A=12 \end{gathered}[/tex]second are is 12 square ft
Add areas to find total area
[tex]10+12=22[/tex]total area of the desk is 22square ft
[tex]22ft^2[/tex]
