R-24

What is the relationship between two similar figures? (Reptiles)

Scale Factor- Number I multiply side length or perimeter by to get similar figure

Side Length- in proportion smaller side length x scale factor= bigger side length

Perimeter- small perimeter x scale factor= bigger perimeter

Area- bigger shape side lengths are a multiple of smaller shape side lengths



If my original area is 3 and my scale factor is 2 (twice as big), how can I figure out what that new area is?



If my original area is 6 and I have a scale factor of 3(3 times as big), how can I figure 

 Rule: original area x (scale factor)^2 = bigger area

(scale factor)^2= scale factor x scale factor
