PLEASE ANSWER FOR BRAINLIEST!!

First find the area of the Room 30 x 30 = 900

We know each triangle can take up 112.5 sq ft
divide these numbers to find how many will be needed.

Then you can add the 112.5 four times to find how much it will cover. Subtract the 900 with that number and that will be what is left.
