# Hectares

The rectangular land is 350m long and 200m wide. Calculate the area in hectares.

Correct result:

S =  7 ha

#### Solution:

$a=350 \ \text{m} \ \\ b=200 \ \text{m} \ \\ \ \\ S_{1}=a \cdot \ b=350 \cdot \ 200=70000 \ \text{m}^2 \ \\ \ \\ S=S_{1} \rightarrow ha=S_{1} / 10000 \ ha=70000 / 10000 \ ha=7 \ ha=7 \ \text{ha}$
