Parking car capacity

The department store has a rectangular car park with a length of 48 m and a width of 65 dm. How many cars can there fit when each car needs 2.5 m²?

Final Answer:

n =  124

Step-by-step explanation:

$$\begin{gathered} a=48\text{m} \\ b=65\text{dm}\to \text{m}=65:10\text{m}=6.5\text{m} \\ {S}_1=2.5{\text{m}}^2 \\ S=a\cdot b=48\cdot 6.5=312{\text{m}}^2 \\ {n}_0=S/S_1=312/2.5=\frac{624}{5}=124\frac{4}{5}=124.8 \\ n=\lfloor n_0\rfloor =\lfloor 124.8\rfloor =124 \end{gathered}$$
