a certain corner of a room is selected as the origin of a rectangular coordinate system. if a fly is crawling on an adjacent wall at a point having coordinates (5.7 m, 5.7 m) what is the distance of the fly from the corner of the room?

Apply Pyth. theorem and u will get :
r = sqrt(5.7^2 + 5.7^2) = 8.06 m
r = sqrt(5.7^2 + 5.7^2) = 8.06 m
