Given that

The length of the rectangular field is 0.35 km and the width is 0.2 km. And we have to find the area of this field.

Explanation -

The formula for the area of the rectangle is


Area=length* breadth

On substituting the values we have


\begin{gathered} Area=0.35*0.2\text{ km}^2 \\ Area=0.07\text{ km}^2 \end{gathered}

Since the conversions are given as


\begin{gathered} 1\text{ km = 1000 m}^{\text{ }}=10^3\text{ m} \\ 1\text{ km}^2=10^6\text{ m} \end{gathered}

So the required answer in sq meters will be


\begin{gathered} Area=0.07*10^6\text{ m}^2 \\ Area=7*10^4\text{ m}^2=70000\text{ m}^2 \end{gathered}So the final answer is 70000 sq meters.
