how can the length of the small shaded triangle's hypotenuse have a length (125 ft ?) greater than the side of the large square (25 ft ?) ???
maybe it is supposed to be 12.5ft, or could it have been 125cm. I couldn't tell by the computer and I can't open it up now. the answer is 195 sq ft. i just wanted to figure out how to work the problem, can anyone help?
