OpenStudy (michele_laino):

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

OpenStudy (horsegal244):

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):

that's right, better is 6.67 feet

OpenStudy (horsegal244):

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=...

OpenStudy (horsegal244):

8.3 run on

OpenStudy (michele_laino):

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):

do i multiply?

OpenStudy (michele_laino):

yes!

OpenStudy (horsegal244):

55.5611

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

OpenStudy (horsegal244):

ok so i would change the bottom part to that

OpenStudy (michele_laino):

yes!

OpenStudy (horsegal244):

does it sound good for essay?

OpenStudy (michele_laino):

yes!
