The given scale is 1:600.

The dimensions of the drawing are 5 by 15.

We just have to multiply each dimension by 600.


\begin{gathered} 5*600=3000 \\ 15*600=9000 \end{gathered}

So, the dimensions of the actual area are 3,000 cm and 9,000 cm. But, we know that 1 meter equals 100 centimeters, let's transform.


\begin{gathered} 3000cm\cdot\frac{1m}{100\operatorname{cm}}=30m \\ 9000\operatorname{cm}\cdot\frac{1m}{100\operatorname{cm}}=90m \end{gathered}

Then, we multiply the dimensions to find the area.


A=30m*90m=2700m^2

Hence, the actual area is 2,700 square meters.
