Pia printed 2 maps of a walking trail. The length of the trail on the first map is 8 cm. The length of the trail on the second m

Marianna [84]

The scale factor from the first map to the second map can be determined by:

scale factor = (length of trail in first map) / (length of trail in second map)

8 cm / 6 cm = 1.33

The landmark on the first map is a triangle with side lengths of 3mm, 4mm, and 5mm.

3mm = 3 * 1.33 mm = 3.99mm
4mm = 4 * 1.33 mm = 5.32mm
5mm = 5 * 1.33 mm = 6.65mm
