\n" ); document.write( "Note: \"A%5BT%5D+=+%281%2F2%29b%2Ah\"
\n" ); document.write( "One leg\"highlight%28y%29\" of a right triangle is 7cm shorter than the other leg\"highlight%28x%29\".
\n" ); document.write( "Question states*** area is 30cm^2
\n" ); document.write( " \"30cm%5E2+=+%281%2F2%29x%2Ay\" || \"+y+=+%28x-7%29\"
\n" ); document.write( " 60 = x(x - 7)
\n" ); document.write( " x^2 - 7x - 60 = 0
\n" ); document.write( " (x - 12)(x + 5) = 0 || Tossing out negative solution for unit measure
\n" ); document.write( " x = 12cm and y = 5cm
\n" ); document.write( "Applying the Pythagorean Theorem: \"sqrt%2812%5E2+%2B+5%5E2%29+=+13cm\"
\n" ); document.write( "P = 12cm + 5cm + 13cm = 30cm \n" ); document.write( "
\n" );
