Answer 1

S = a * b
The room is 5.4 meters long and 4 7/8 meters wide. = >
a = 5.4 
b= 4 +7/8
S= $\frac{54*39}{10*8}$=$\frac{27*39}{10*4}$=26.325 meters ^ 2 - square yards of carpet
P = 2(a+b)=2*(54/10+39/8)=2*(216/40+195/40)=2*((216+195)/40)=
=216+195)/20=411/20=20.55 meters -  yards of wallpaper border
