I'm really confused with a word problem trying to find the sides of a triangle with just an altitude or a perimeter.

How would I found the length of a side of an equilateral triangle with an altitude of 24? I know altitude divides the triangle in half, so would it be a 45-45-90 triangle?

Also how would I find the altitude of an equilateral triangle with a perimeter of 45?

Thanks for your help.
