Use trigonometry and other methods to calculate and estimate the area of a region. 1) Charlie the goat is tied with a 10 meter rope to the corner of a non-rectangular building. The sides closest to him have lengths 7 meters and 12 meters. Choose a building shape and determine the area of grass that Charlie can eat. (triangle? Parallelogram? Which one is better) 2) Choose another building shape to investigate - be creative! It is unlikely that you will be able to find an exact solution - you are being asked to estimate reasonably and find a solution that makes sense.
