 Question 45325: I guess this question would be under Geometry- I couldn't tell. My daughter has to find the perimeter, and then the area (two different questions) and show her work for a figure that is 6 feet on three sides, then the fourth side has an arc with "3" written in bold. I don't know if I showed her right on the perimeter- but would it be 6ft. time 3 sides, plus 9 more feet for a total perimeter of 27 feet? If that is right, how would we show that? Also, I know how to find area, but how do you do that with the arc or semi circle attached to the square? Thank you! Click here to see answer by tutmath(14)
