Hello!\r
\n" ); document.write( "\n" ); document.write( "Let's say that x is the smaller polygon, it says that the scale is 5:2. Then we can say that $\"5%3A2=100%3Ax\"$ . For this propotion you can say that $\"5%28y%29=100\"$ and $\"2%28y%29=x\"$ . 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.\r
