A pinhole camera is a simple camera that has a lightproof box with one tiny hole. As light enters the small hole, an inverted image of what's in front the camera appears on the opposite side of the box. Savanna has set up a pinhole camera on a flat stand, and it captures the image of a tree which is standing almost perfectly upright. If the image inside the pinhole camera's box is 1 foot tall, the width of the box is 1.5 feet, and the distance from the tree to the front side of the pinhole camera is 14 feet, how tall is the tree? Round the answer to one decimal place, if necessary.
