Answer:
125.141
Step-by-step explanation:
Assuming that this is an equilateral triangle, I am going to divide this triangle in half to get a right triangle.
17 is our hypotenuse
17/2 = 8.5, this is one of our legs
The other leg is our height, which we will find.
We use Pythagoras Theorem to find the height/leg: 

= 14.72243186
Now, we use another formula to find the area of the triangle: 
14.72243186 × 17 = 250.2813416
250.2813416 ÷ 2 = <u>125.1406708</u>
