assuming is is roughtly a rectangle
area of rectangle=length times width
length=20ft
width=12 ft
area=length times width=20 times 12= 240 square feet
how many packages?
1 pack times x is at least 240
1 pack times x>240
50 times x>240
divide both sides by 50
x>4.8
you can't buy 0.8 pack, so round up
5 packs needed
1) x1= -8 , x2=16
2) x= 11
3) 7/8 or 0.875
