Find the dimension of a rectangular Persian rug whose perimeter is 18 ft. and whose area is 20 ft^2?\r
\n" ); document.write( "\n" ); document.write( "what are the length and width?
\n" ); document.write( "-------------------------------------
\n" ); document.write( "Perimeter = 2(L + W)
\n" ); document.write( "----------------\r
\n" ); document.write( "\n" ); document.write( "L+W = 9
\n" ); document.write( "LW = 20
\n" ); document.write( "-----
\n" ); document.write( "L = 9-W
\n" ); document.write( "----
\n" ); document.write( "Substitute for \"L\" and solve for \"W\":
\n" ); document.write( "(9-W)W = 20
\n" ); document.write( "-W^2+9W = 20
\n" ); document.write( "---
\n" ); document.write( "W^2-9W+20 = 0
\n" ); document.write( "-----
\n" ); document.write( "(W-5)(W-4) = 0
\n" ); document.write( "If W = 5, L = 4
\n" ); document.write( "If W = 4, L = 5
