since the base of your room is 4 inches long in your drawing, then the real measure is:
4*20=...
OpenStudy (horsegal244):
80
OpenStudy (michele_laino):
exact 80 inches, and 80 inches means
80/12=...feet

I don't get it...
OpenStudy (michele_laino):
since we have 1 foot = 12 inches
then we have to divide 80 by 12, in order to know how many feet is long the base of your kitchen
OpenStudy (horsegal244):
Oh ok
OpenStudy (horsegal244):
6.6 run on
OpenStudy (michele_laino):

ok
OpenStudy (michele_laino):
similarly for the height of your kitchen which is 5 inches in your drawing, so the real length is:
5*20=...
OpenStudy (horsegal244):
100
OpenStudy (michele_laino):
ok! so we have to divide 100 by 12 in order to know that length in feet:
100/12=...

that's right!
so we can say that the dimensions of your kitchen are:
6.67 feet
8.33 feet
OpenStudy (michele_laino):
the the requested area is:
6.67*8.33=...
OpenStudy (horsegal244):

OpenStudy (michele_laino):
correct! the area of your kitchen is:
A=55.5611 feet^2
OpenStudy (horsegal244):
So i can say
The dimensions are: 6.67ft and 8.33ft
The area is 111.12
OpenStudy (michele_laino):
the area is 55.5611
OpenStudy (horsegal244):
Oh i thought * means multiply by 2
OpenStudy (michele_laino):
no, since it is the area of a rectangle
