Question

A scale drawing of a lake has a scale of 1 cm to 80 m. If the actual width was f the lake is 1,000 m, what is the width of the lake on the scale drawing?

Answer 1

Answer:

12,5 centimeters.

Step-by-step explanation:

We take the following proportion

$\frac{1 cm}{80m} = \frac{x}{1000m}$

Which becomes:

$1000 = 80x$

And then, we clear out the variable x:

$\frac{1000}{80}=\frac{100}{8}=\frac{50}{4}=12,5$

And this means that the width of the lake on the scale drawing will be 12.5 cm.
