Answer: 96 units
Step-by-step explanation:
3 by 4 Right Triangles: [tex](3*4)/2[/tex] for each triangle, so [tex]2((3*4)/2)=12[/tex] units for both two triangles.
Middle Rectangles: Since all of the 3 rectangles have the same height, we can add together the widths to get [tex](3+4+5)*7=12*7=84[/tex] units.
Add them together: [tex]84+12=96[/tex] units
I hope it helps!
