It takes 150 square feet of wood flooring to cover a 13 by 11 foot room, counting waste. At this rate, how much flooring, to the nearest foot, would it take to cover a 15 by 20 foot room?
:
You could us a ratio equation:
:
Let x = amt of flooring required for a 15 by 20 ft room
:
Actual area of the 13 by 11 ft room
13 * 11 = 143 sq ft
:
Actual area of the 15 by 20 ft room
15 * 20 = 300 sq ft
:
150%2Fx = 143%2F300
Cross multiply:
:
143x = 150 * 300
:
143x = 45000
x = 45000%2F143
x = 314.6853 ~ 315 sq ft of flooring required for a 15 by 20 ft room
