Area of rectangle

Calculate the rectangle area in square meters whose sides have dimensions a = 80dm and b = 160dm.

Correct answer:

S =  128 m²

Step-by-step explanation:

$$\begin{gathered} a=80\mathrm{/}10=8\text{ m } \\ b=160\mathrm{/}10=16\text{ m } \\ S=a\cdot b=8\cdot 16=128{\text{m}}^2 \end{gathered}$$
