According to the scale, 6000 times two thousandths =3 4000 times two thousandths =2.

So draw a rectangle with a length of 3cm and a width of 2cm.

5. Measure the width and height in centimeters with a ruler or triangle, and then multiply them by 200, which is the actual width and height. Note that the unit is centimeters.

1. Divide the distance on the drawings of Party A and Party B by the actual distance to get the ratio:

160km =16000000cm

4 divided by1600000 =1/4000000.

Divide the distance on the B-C diagram by the scale to get the actual distance, that is

8.9 times 4000000=35600000 (cm) =356 km.
