For a project in her Geometry class, Charlotte uses a mirror on the ground to measure the height of her school building. She walks a distance of 7.45 meters from the school, then places a mirror on flat on the ground, marked with an X at the center. She then steps 2.5 meters to the other side of the mirror, until she can see the top of the school clearly marked in the X.
