Question

What is the scale factor if a1 is 15 and a2 is 60?

Answer 1

If area 1 is 15, and area 2 is 60, we need to divide the larger area by the smaller area. This gives us our scale factor.

60 / 15 = 4.

Your scale factor is 4, meaning for every 1 of area1 is 4 for every area2.

I hope this helps!
