Let the length of a rectangle is \"x\", then the width is \"x-5\".
\n" ); document.write( "The perimeter is \"2%2A%28a+%2B+b%29+=+2%2A%28x+%2B+%28x+-+5%29%29+=+30\".
\n" ); document.write( "Then:
\n" ); document.write( "\"2%2A%28x+%2B+x+-+5%29+=+30\"
\n" ); document.write( "\"2%2A%282x+-+5%29+=+30\"
\n" ); document.write( "\"4x+-+10+=+30\"
\n" ); document.write( "\"4x+=+40\"
\n" ); document.write( "\"x+=+10\"
\n" ); document.write( "\"x+-+5+=+5\"\r
\n" ); document.write( "\n" ); document.write( "Answer: the length of a rectangle is 10 inches and the width is 5 inches.
