7/6π" (or 1.17π"). To find the circumference (therefore the distance the hand travels) you do 2rπ (radius is 7in), which is 14π, then divide it by 12 bc the hand is only moving five minutes (which is simplified to 7/6π). You can't simplify π.
I believe the shorter sides are 5 feet and the longer ones are 10. This is because when you add up the two shorter sides as 10, and the other two as 20, then add them up to 30. That's the perimeter. For the area, you would do 10•5 to get 50 for the area
