The area would be 324 yards square. Since the height is already found, you multiply 15 by 21 2/3 yards.
Hope this helped :)
1. Total area of water = 352,000,000 + 9 * 10^6
= 352,000,000 + 9,000,000 = 361,000,000 = 3.61 * 10^8
Fraction of the surface covered by water = 3.61 * 10^8 / 5.1 * 10^8
= 3.61 / 5.1 = 0.707843 = 70.78 % to nearest hundredth of a percent.
