Question

The scale of a map is 1 : 20000 . What area does 8cm^2 represent?

its my math homework and i need help:")

Answer 1

Step-by-step explanation:

On the first map the scale is 1:20000 and the area of the forest is 50 cm^2. Now on the other map the same 200* 10^8 is represented by 8 cm^2. So the scale is sqrt [ 200* 10^8 / 8 ] = sqrt [ 25* 10^8 ] = 5* 10^4 = 50000.
