10. CONNECTING TO REAL LIFE You help a park ranger find a rectangular region of land to plant new trees. You divide the region using a coordinate plane in which the coordinates are measured in yards. Three vertices of the region are (3, 5), (3, 85), and (133, 5). Find the fourth vertex. Then find the perimeter and the area of the region.

• A. (133, 85); B. 420 square yards C.10,400 yards
• A. (133, 85); B. 420 yards; C 10,400 square yards
• A. (133, 85); B. 420 square yards C.10,400 square yards
• A. (33.85); B. 420 yards C.10,400 square yards
