We find the surface area of the figure by dividing the figure into smaller ones. This is:
Area 1, rectangle:
[tex]A=\text{length}\times width=2.2\times1.6=3.52[/tex]Area 2, triangle:
[tex]A=\frac{base\times height}{2}=\frac{2\times0.9}{2}=0.9[/tex]Area 3, rectangle:
[tex]A=1.6\times0.9=1.44[/tex]Area 4, triangle:
[tex]A=\frac{2\times0.9}{2}=0.9[/tex]Area 5, rectangle:
[tex]A=2\times1.6=3.2[/tex]Therefore, the surface area of the ramp is:
[tex]A=A1+A2+A3+A4+A5[/tex]Substitute the corresponding values:
[tex]A=3.52+0.9+1.44+0.9+3.2=9.96[/tex]Answer: 9.96 m^2
