The similarity ratio of two similar polygons is 2: 3. compare the smaller polygon to the larger polygon. find the ratio of their areas.

To find the ratio of the areas you would have to square the scale factor so the ratio of the areas would be 4:9

hope this helped!

Okay i will add you

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
