Answer :
S = a * b
The room is 5.4 meters long and 4 7/8 meters wide. = >
a = 5.4
b= 4 +7/8
S= [tex] \frac{54*39}{10*8} [/tex]=[tex] \frac{27*39}{10*4} [/tex]=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

- The yards of carpet will she need 26.325 meters square.
- The wallpaper border will she need 20.55 meters yards.
We have given that, Margo wants a new carpet and new wallpaper border for her bedroom.
The room is 5.4 meters long and 4 7/8 meters wide.
What is the formula for a rectangle?
A=length (width)
S = a * b
The room is 5.4 meters long and 4 7/8 meters wide.
a = 5.4
b= 4 +7/8
S= (54)(39)/10(8)
S=(27)(39)/(10)(4)
S=26.325 meters square
Therefore the 26.325 meters square yards of carpet
Perimeter of rectangle is
P = 2(a+b)
P=2*(54/10+39/8)
P=2*(216/40+195/40)
P=2*((216+195)/40)
P=216+195)/20
P=411/20
P=20.55 meters
Therefore, The 20.55 meters yards of the wallpaper border.
