20 102.3 rounded down is 100 4.7 rounded up is 5. 100 / 5 = 20 because 5 * 20 = 100
The first step in solving this problem is to compute for the
area of the rectangular wall. The formula in computing the area of a rectangle
is:
A = LW
Substituting the given measurements in the problem to the
formula:
A = 13 (12)
A = 156
Therefore, the area of the wall is 156 square feet. To compute
the wallpaper cost of the wall, you have to multiply the cost per square foot
to the total area.
$8 per square foot x 156 square feet = $1,248
Therefore, the wallpaper cost for the wall is $1,248
