25 metres tall.
Explanation:
The heights of the trees are directly proportional to the length of their shadows because at the same time of day, the sun will be at the same angle in the sky.
The trees and their shadows form 2 similar triangles:
Write as a proportion:
<span><span>heightshadow</span> <span>x20</span>=<span>1512</span></span>
<span>12x=20×15</span>
<span>x=<span><span>20×15</span>12</span></span>
<span>x=25</span> metres tall.
As check: find the constant for each tree:
<span><span>1512</span>=1.25 and <span>2520</span>=<span>1.25</span></span>
