Answer:
64.8
Step-by-step explanation:
If this is an equilateral triangle, we need half of it to find the height which is a leg of a right triangle with a hypotenuse of 15. That means that the base of this half triangle is 7.5. Use Pythagorean's Theorem to fine the height.
![x^{2} =(15) ^{2} -(7.5) ^{2}](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20%3D%2815%29%20%5E%7B2%7D%20-%287.5%29%20%5E%7B2%7D%20)
. x = 12.99 or 13
Because you know the area and that the shape is a square... if the side length is "s"... to find "s" you would say...
s²=1.69
Take the root of both sides and...
s=1.3 km
