INTRODUCION.
</span>
<br />
<br />
We use mmeasurements to know the value of land, the value o the whole of country, of District, of Province nd of certain figures(square,tringle, Parallelograme,....;). Those
<br />
measurements appear two times in multiplication.
<br />

<ul>
<li>
<span style="font-size: medium;">
For example thhe surface of Rwanda is 26 338km
<sup>

</sup>
, the number of population estameted per km
<sup>
2
</sup>
is .......... .
</span>
</li>
<li>
<span style="font-size: medium;">
A recctangle which has 20m of width and 30m of length as its sides has 600m
<sup>
2
</sup>
</span>
of surface.
</li>
<li>
<span style="font-size: medium;">
The land that has the same dimensions with above recctangle , we measure it in hectares, ares or centiares(30m*20m)=600ca.
</span>
</li>
</ul>
<p>
In this milestone, we will talk about meeasuremennts of surface and mmeasurements of land.
