Answer:
The kitchen has a bigger actual area than the bedroom
Step-by-step explanation:
Here, we want to know the compartment with the bigger area
Since the bedroom has a drawing measure of 1 to 40; compared to the actual measurement;
The real dimensions will be;
10 * 40 and 18 * 40
= 400 by 720
So, its area which is length * width will be;
400 cm * 720 cm = 288,000 cm^2
we can see that the kitchen with an area of 300,000 cm^2 is bigger than this area of the bedroom
