Answer:
7200 cm^2
Step-by-step explanation:
The kitchen dimension on the drawing of 14 cm corresponds to an actual kitchen dimension of 40·14 = 560 cm.
The kitchen dimension on the drawing of 22 cm corresponds to an actual kitchen dimension of 40·22 = 880 cm.
The actual kitchen area is ...
Area = length · width = (880 cm)(560 cm) = 492,800 cm^2.
__
The difference between this area and the bedroom area is ...
500,000 cm^2 -492,800 cm^2 = 7200 cm^2
The kitchen is 7200 cm^2 smaller than the bedroom.
