Archaeologists attempt to reconstruct past ways of life by examining preserved bones, the ruins of buildings, and artifacts such

During a dig, three corners of a triangular building have been partially unearthed at (-1, 6), (4, 5), and (-3, -4). If each square on the grid measures one square foot, estimate the area of the floor of the building. a. about 50ft^2
