A picture is 42 cm by 36 cm. A scale diagram of the picture must fit in a space that is 3 m by 2 m. Write a reasonable scale for the scale diagram.

Answer 1

Wow, a scale that increases...

first, which measurement will limit the scale?
300cm/42cm=7.14
200cm/36cm=5.55

so a scale of 5.5:1 will work, but honestly, most folks would scale it at 5:1
scale dimensions: 42*5=2.10m
36*5=1.8m
