I was thinking that you have to set up a proportion like 4/3 = 25/x, but I'm not sure if this is correct or not. \n" ); document.write( "
Algebra.Com's Answer #279159 by scott8148(6628) You can put this solution on YOUR website! the diagonal is the hypotenuse of a right triangle formed by the length, width and diagonal\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "if the length-to-width ratio is 4:3, then the width-to-length-to-diagonal ratio is 3:4:5 (look familiar?)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "if k is the proportionality constant (fudge factor), \n" ); document.write( "then ___ 3k:4k:5k = W:L:25 \n" ); document.write( " |
