Map scale 3 mm = 27 km measured length = 3.5 actual length blank

First, let's find the actual length represented by 1mm. Here is the original equation:

3mm = 27km

Divide 3 from both sides of the equation:

1mm = 9km

We have now proven that 1mm is equal to an actual length of 9km. Now multiply the known length of 1mm by 3.5 to find the missing value:

3.5(9) = x

Simplify the left side of the equation:

31.5 = x

We have now proven that 3.5mm is equal to 31.5 km.

I hope this helps!
