Find area of room
aera=legnth wtimes width
in a square, legnth=width
aera=legnth^2

14*12=168 inches
area=168^2=28224 square inches
how many tiles will cover all of floor?

Step-by-step explanation:
m=p/3
t=(3/10)(1-1/3)
t=(3/10)(2/3)=p/5
p-p/3-p/5=35

7p/15=35
7p=525
p=75
So the book has 75 pages.
