I think one side is 25 yards, so answer is 25². that makes the area of the chicken pen to be 625 sqaure yards.
Part B a yard is exactly three feet, so the power becomes 75², and the area is 5625 square feet.
third question: not sure what the only use once is, but 2^4 and 4² could be the first one, they both equal 16. The second could be 3^4 and 9^2, which are both 81.
