Question

Help please with math

Answer 1

Explanation:

The perimeter of the triangle is all the sides added up.

But let's first make everything in terms of

`3√(45) =3√(9*5) = 9√(5)`

`√(80) =√(16*5) =4√(5)`

Now that everything is in terms of
`√(5)` , we can add them all up.

`√(5) + 9√(5) +4√(5) = √(5) (1 +9+4) = 14√(5)`

The perimeter is
`14√(5)`

Hope that helps!
