Answer:
15 cm
Step-by-step explanation:
The area of an equilateral triangle is:
, where a is the length of one side.
We can find the value of a (the length) by:
![\frac{25\sqrt{3} }{4} = \frac{\sqrt{3} }{4}a^2](https://tex.z-dn.net/?f=%5Cfrac%7B25%5Csqrt%7B3%7D%20%7D%7B4%7D%20%3D%20%5Cfrac%7B%5Csqrt%7B3%7D%20%7D%7B4%7Da%5E2)
![a^2 = 25](https://tex.z-dn.net/?f=a%5E2%20%3D%2025)
a = 5, so the side length of this triangle is 5 cm.
The perimeter of an equilateral triangle will be 3 times the length.
![3\cdot5=15](https://tex.z-dn.net/?f=3%5Ccdot5%3D15)
