| First of all, let’s determine the area of one piece of wallpaper, the length of which is 12 m, and the width = 5 dm (0.5 m, assuming that 1 m = 10 dm).
The area of the rectangle is calculated by the formula:
S = a * b.
Substitute the known values:
S = 12 * 0.5 = 6 m².
Ten such pieces can be pasted over:
10 * 6 = 60 m².
