Answer 2

Answer:

Step-by-step explanation:

“2a” in this diagram is the side length of the equilateral which in your case is “a”

The height is equal to half of the side length times the square root of 3.

So in your case, the height is a*√3/2

Another way to find this would be to set areas equal to each other

(a^2)*√3/4 = a*h/2

“a” being the base

Solving for “h” gives you:

h = a*√3/2
