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!

Question 52281: If AC=62, find the value of x. Then find AB and BC.
Picture: shows a line with 3 points on it. A, B, and C. Points AB=3x-4 and points BC=3x-4.
When finding x, I got 10.3 since AB and BC both are 3x-4..does that make them congruent...so AB and BC would both equal 26.9? [ 3(10.3)-4 = 26.9 ]

Thank you.
