the shorter leg of a 30-60-90 triangle is 9.4 inches long. find the perimeter.
the perimeter of the standard 30-60-90
is 1+√3 + 2 = 3+√3
so the shortest side was stretched by a factor of 9.4, so all sides where stretched by 9.4
perimeter of larger triangle = 9.4(3+√3)
I will let you do any button-pushing to get a decimal answer.
