Chapter 8 - Geometry - 8.9 Similar Triangles - 8.9 Exercises: 27

Answer

$110$ m

Work Step by Step

Since the triangles are similar, we can set up a proportion between the small and large triangle sides: $\displaystyle \frac{n}{220~m}=\frac{50~m}{100~m}$ Cross-multiply and solve for $n$: $100n=50*220$ $100n=11000$ $n=11000/100$ $n=110$ m
