Answer:
+ 300√2 ft
Step-by-step explanation:
We assume that all walls have the same length: 300 ft. Then the diagonal distance from one vertex of the 300 ft by 300 ft base of the room is found using the distance Pythagorean Theorem: d = sqrt(300^2 + 300^2) ) = sqrt(18*10^4) = +3√2*√10^4 = + 300√2 ft.
