Answer:
perimeter of the figure: [tex]32m^3+11m^2-39m+1[/tex]
Step-by-step explanation:
perimeter = sum of all the sides.
→ [tex]20m^2+12m^2+4m^3-24m^2+1+20m^3+3m^2+m+8m^3-40m[/tex]
→ [tex]4m^3+20m^3+8m^3+20m^2+12m^2-24m^2+3m^2+m-40m+1[/tex]
→ [tex]32m^3+11m^2+m-40m+1[/tex]
→ [tex]32m^3+11m^2-39m+1[/tex]
