How many of 30*30 are in 800*700? The tile area units kept as square centimeters, and the room unit converted to square centimeters.

%28800%2A700%29%2F%2830%5E2%29=%2856%2F9%29%2810000%2F100%29
100%2856%2F9%29
%286%261%2F9%29%2A100
highlight%28611%261%2F9%29, probably the one-ninth is small enough to ignore. Maybe easy enough to cut the right piece to fill what is empty.
