Answer:
11:10
Step-by-step explanation:
If the scale factor for similar shapes is a:b
We know the ratio of the sides is a:b
areas is a^2 : b^2
volumes is a^3 : b^3
The ratio of the areas is 121:100
Take the square root to find the scale factors
sqrt(121) : sqrt(100)
11:10
This is also the ratio of the sides
