\n" ); document.write( "First, I am given a picture of two, similar rectangles. One is larger than the other. The smaller one has x and y on both bases of it. The larger rectangle has 8 and 20, in that order, on its two bases. It gives the area of the smaller rectangle and asks for you to solve for variables x and y. I do not want an answer but a walk through on how to get the answer.

\n" );
document.write( "Hi
\n" );
document.write( "It gives the area of the smaller rectangle, let's say it is 40
\n" );
document.write( "larger rectangle Area = 160
\n" );
document.write( "Ratios of the Areas is the ratio of corresponding sides squared.
\n" );
document.write( " (8/x)^2 = 160/40 = 4
\n" );
document.write( " 64/x^2 = 4
\n" );
document.write( " 16 = x^2
\n" );
document.write( " 4 = x       (Tossing out the negative solution for unit measure)
\n" );
document.write( "repeat
\n" );
document.write( "(20/y)^2= 4
\n" );
document.write( " 20^2/y^2 = 4
\n" );
document.write( "400/4 = y^2
\n" );
document.write( " 10 = y
\n" );
document.write( " \n" );
document.write( "

\n" );
