Question 107329
Hello!

Let's say that x is the smaller polygon, it says that the scale is 5:2. Then we can say that {{{5:2=100:x}}}. For this propotion you can say that {{{5(y)=100}}} and {{{2(y)=x}}}. To find y you should divide 100 by 5, the result is 20. 20 is y so that means 2(20) is x. 2(20)=40. That means that x is 40.


The smaller polygon has the area of 40.




I hoped I helped you!
