Answer:

The area of the dam = 175,000 cm^2

Step-by-step explanation:

We know that the ratio of the map to the real area is


\frac{\text{map}}{\operatorname{Re}al}=(1)/(50000)

Now we want the real area of the dam if its area on the map is 3.5 cm^2.

Let us call x the real area of the dam, then we have


(1)/(50000)=(3.5)/(x)

cross multipication gives


x=3.5*50000
\boxed{x=175,000\operatorname{cm}^2}

which is our answer!
