A triangular region of farmland has become overrun with deer and will be open to the public for hunting to reduce the population. In order to know how many hunters to allow on the land at one time, you need to know the area of the region in square miles. In order to estimate the area of the region, you travel from the southernmost vertex C north 20 miles then west 24 miles (for vertex B), and from the southernmost vertex C you travel 54 miles north then 7 miles east (for vertex A). Use a graphing utility to approximate the number of square miles of land.
A. 578 square miles
B. 51 square miles
C. 119 square miles
D. 429 square miles
E. 718 square miles
