Aboard an orbital station, Nova and Luna needed to replace a damaged rectangular satellite panel measuring 6 meters by 4 meters. Their supply room contained only 24 square meters of material, so they could not afford any waste. One design used rectangular sections, while another divided the panel into right triangles with legs of 3 meters and 4 meters. Luna calculated that each triangle had an area of 6 square meters, so four triangles would cover exactly 24 square meters. Nova checked the angles and side lengths. Two matching right triangles could be joined along their 5-meter sides to form a 3-meter by 4-meter rectangle, and two such rectangles would fit together to cover the damaged 6-meter by 4-meter region without gaps. Since the triangular design used exactly the available material and formed the required shape, they selected it. The replacement fit perfectly, and the satellite was ready to return to service.
