We can write a proportion: 15 m is to 12 m as some other height
![h](https://tex.z-dn.net/?f=h)
is to 20 m
So we get
![\frac{15}{12}=\frac{h}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B12%7D%3D%5Cfrac%7Bh%7D%7B20%7D)
![\rightarrow 15*20=12h](https://tex.z-dn.net/?f=%5Crightarrow%2015%2A20%3D12h)
![\rightarrow 12h=300](https://tex.z-dn.net/?f=%5Crightarrow%2012h%3D300)
![\rightarrow h=25](https://tex.z-dn.net/?f=%5Crightarrow%20h%3D25)
So the second tree is 25 m tall.
