Yusuf's partner is 1.35 meters tall, and from the mirror to Yusuf's partner is 2.15 meters. Therefore, the distance from the mirror to Yusuf's eyes is 2.15 - 1.35 = 0.8 meters. By similar triangles, the height of the school is 13.95 * 1.35 / 0.8 = 23.565 meters. Rounded to the nearest hundredth of a meter, the school is approximately 23.57 meters tall.
