How many square feet of the entrance way floor consists of white tiles?
(6.5 x 4) squared = 6.5 x 4 = 26 squared= 676 square feet
No because an acute triangle is less than 90 degrees and a right angle is 90 degrees so it doesn't work.

The answer is -a^2 + 3a +1
Let me know if it's right, this is what I got when I did the problem :)
