Perimeter is the surrounding of a shape area is the space inside a shape
M = (t+1)/(t-3)
m(t-3) = t+1
mt-3m = t+1
(m-1)t = 3m+1
t = (3m+1)/(m-1)
1 yard= 3 feet
4*3=12 (we do this to find how long the floor is)
10*12=120 (this is in feet, but it needs to be converted to yards)
120/3=40
You need 40 yards of tile
Start with the bigger rectangle and remove the white corners. Starts with 1800 then remove 100, 150 and 150
From 7-12
