What is the perimeter of an equilateral triangle whose height is 2 square root of 3

Step-by-step explanation:

If we half the base of the equilateral triangle, which has a length of xcm, we can form a right-angled triangle with a base of x/2 cm and height 2√3 cm.

Now using Pythagoras' Theorem we solve for the hypotenuse:

x must be positive as it is a length so we multiply 4 by 3 to get the perimeter of 12.
