The drawing of the apartment is in the ratio of 1:200. The living room has dimensions of 2cm x 3cm in the picture. How many square meters does the living room have?

Correct answer:

S =  24 m²

Step-by-step explanation:

$$\begin{gathered} M=200 \\ a=2\text{cm}\to \text{m}=2:100\text{m}=0.02\text{m} \\ b=3\text{cm}\to \text{m}=3:100\text{m}=0.03\text{m} \\ A=M\cdot a=200\cdot 0.02=4\text{m} \\ B=M\cdot b=200\cdot 0.03=6\text{m} \\ S=A\cdot B=4\cdot 6=24{\text{m}}^2 \end{gathered}$$
