Question

Please Help:((( Please explain! :( What does S equal? (Explain!) Please asap:(((

Answer 1

So because this quadrilateral's sides are the same, S, this means that this is a square. With that in mind, the area of a square is $A=x^2$, with x = sides. Since we have the area, we can solve for the side as such:

$1.69=S^2\\ \sqrt{1.69}=\sqrt{S^2}\\ 1.3=S$

In short, S = 1.3 km.
