3m east and 15m west evens out to 12m west. That's one side of a triangle. The second side is 2.5m north.
The third side is your displacement,
use Pythagorean's Theorem to determine this.
a^2+b^2=c^2, that works out to 12^2+2.5^2=c^2.....144+6.25=c^2
<span>150.25=c^2
and
finally
c=12.26,
or 12m</span>
