In her dorm room, Erica wants to string small white lights across one diagonal of the ceiling. (Assume there is an electrical outlet in the upper corner of the room.) How many feet of lights does Erica need if her room is 14 ft by 10 ft? Round up to the nearest foot to guarantee she will have enough
-------------------
diagonal of the ceiling = sqrt(14^2 + 10^2)
d = sqrt(296)
d = 17.20 ft.
