A surveyor needs to measure the distance CD, across the lake. Beginning at E, she locates the mid-point, G, of DE and the mid-point of F, of CE. She then measures FG. What is CD?

CD is the measurement across the lake. CD is double the measurement of FG. To find CD, you need to multiply the measurement of FG by 2. Since the measurement of FG is 45 meters, the distance across the lake (CD) is 90 meters.
