Land acreage calculation

The land has a rectangular shape with 75 m and 450 dm dimensions. Calculate the acreage of the land and, convert the result, and round to whole ares.

Final Answer:

S =  3375 m²
S =  34 a

Step-by-step explanation:

$$\begin{gathered} a=75\text{m} \\ b=450\text{dm}\to \text{m}=450:10\text{m}=45\text{m} \\ S=a\cdot b=75\cdot 45=3375{\text{m}}^2 \end{gathered}$$

$$\begin{gathered} S_1=S\to \text{a}=S:100\text{a}=3375:100\text{a}=33.75\text{a} \\ S=S_2=[S_1]=[33.75]=34\text{a} \end{gathered}$$
