Help please and simplify answer in radical form if needed

Step-by-step explanation:

The area of an equilateral triangle with side length is equal to . Since the perimeter is 24 units and there are three equal sides to an equilateral triangle, each side is units.

Substituting in this value, we get:

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
