Answer:
6.04 kilometers
Explanation:
First, by AA triangle similarity theorem, we know that the two triangles are equal.
So, we can set up a ratio
3,500/2000=4200/x
cross multiplying, we get
3500x=4200*2000
and simplifying, we get x=2400
the distance will be 2,400+4,200=6600 yards
converting to kilometers,
6600*0.0009144=6.04
