Question

a rectangular field is 31 m by 29 m. find its area in m² and in ha.
the area is 899 m².
this is approximately □ ha.
(round to two decimal places.)

Explanation:

Step1: Recall the conversion factor

We know that \(1\) hectare (\(ha\)) \( = 10000\) square meters (\(m^{2}\)).

Step2: Convert the area from \(m^{2}\) to \(ha\)

Let \(A = 899m^{2}\). To convert to hectares, we use the formula \(A_{ha}=\frac{A_{m^{2}}}{10000}\).
Substitute \(A_{m^{2}} = 899\) into the formula: \(A_{ha}=\frac{899}{10000}=0.0899\).

Step3: Round the result

Round \(0.0899\) to two decimal places. Looking at the third - decimal place (9), we round up the second - decimal place. So \(0.0899\approx0.09\).

Answer:

\(0.09\)
