Answer:
Step-by-step explanation:
The perimeter of the triangle is all the sides added up.
But let's first make everything in terms of
[tex]3\sqrt{45} =3\sqrt{9*5} = 9\sqrt{5}[/tex]
[tex]\sqrt{80} =\sqrt{16*5} =4\sqrt{5}[/tex]
Now that everything is in terms of [tex]\sqrt{5}[/tex] , we can add them all up.
[tex]\sqrt{5} + 9\sqrt{5} +4\sqrt{5} = \sqrt{5} (1 +9+4) = 14\sqrt{5}[/tex]
The perimeter is [tex]14\sqrt{5}[/tex]
Hope that helps!
