Question

If the ratio of the area of equilateral triangle A to area of equilateral triangle B is 100 to 25, then what is the ratio of their altitudes?

Answer 1

i know that the side for the 25 area triangle is \[10\sqrt{3}/3\], at least i think

Answer 2

and the triangle with area 100 has a side of \[20\sqrt{3}/3\]

Answer 3

so does that mean the ratio is 2:1?
