The opposite sides of a rectangle are equal
\n" ); document.write( "They could be 12,12,5 , and 5
\n" ); document.write( "or 33,33,8, and 8
\n" ); document.write( "or a, a, b, and b
\n" ); document.write( "The problem says the perimeter is \"264\" meters, so
\n" ); document.write( "\"a+%2B+a+%2B+b+%2B+b+=+264\" meters
\n" ); document.write( "If \"a\" is the length and \"b\" is the width,
\n" ); document.write( "\"a+=+b+%2B+14\" meters
\n" ); document.write( "Plug this expression for \"a\" into the 1st equation
\n" ); document.write( "\"%28b+%2B+14%29+%2B+%28b+%2B+14%29+%2B+b+%2B+b+=+264\"
\n" ); document.write( "\"2b+%2B+28+%2B+2b+=+264\"
\n" ); document.write( "\"4b+=+236\"
\n" ); document.write( "\"b+=+59\"
\n" ); document.write( "\"a+=+b+%2B+14\"
\n" ); document.write( "\"a+=+59+%2B+14\"
\n" ); document.write( "\"a+=+73\"
\n" ); document.write( "The length is 73 meters and the width is 59 meters
\n" ); document.write( "check answer:
\n" ); document.write( "\"a+%2B+a+%2B+b+%2B+b+=+264\"
\n" ); document.write( "\"73+%2B+73+%2B+59+%2B+59+=+264\"
\n" ); document.write( "\"146+%2B+118+=+264\"
\n" ); document.write( "\"264+=+264\"
\n" ); document.write( "and
\n" ); document.write( "\"a+=+b+%2B+14\"
\n" ); document.write( "\"a+=+59+%2B+14\"
\n" ); document.write( "\"a+=+73\"
\n" ); document.write( "OK
\n" ); document.write( "
\n" );
