5 meters.

Step-by-step explanation:

The side of the building and the ground makes an angle of 90°. This means that we don't need to use sine or cosine law to find for the other side.

We can just simply use the Pythagorean Theorem which is

${a}^{2} = {b}^{2} + {c}^{2} \\ {a}^{2} = {3}^{2} + {4}^{2} \\ a = \sqrt{9 + 16 } \\ = \sqrt{25} \\ a = 5$
