HI,
\n" ); document.write( "*Note: the 2 diagonals of a rectangle are Of equal length. Diagonals form a right trangle with the length and width, with the diagonal being the hypotenuse.
\n" ); document.write( ".
\n" ); document.write( "Pythagorean Theorem gives the realtionship between the sides of a right triangle(sides meeting at a right angle) and its hypotenuse.
\n" ); document.write( "\"a%5E2+%2B+b%5E2+=+c%5E2\"
\n" ); document.write( ".
\n" ); document.write( "Question states\r
\n" ); document.write( "\n" ); document.write( "\"12%5E2+%2B+9%5E2+=+c%5E2\"
\n" ); document.write( ".
\n" ); document.write( "\"225+=+c%5E2\"
\n" ); document.write( "c = 15 (the length of each diagonal)
\n" ); document.write( "
\n" );
