Call the length and width, L and W. Then we have
\n" ); document.write( "Perimeter P = 2L + 2W = 62 and
\n" ); document.write( "L = W + 15
\n" ); document.write( "Now substitute this into the first equation and get
\n" ); document.write( "2(W + 15) + 2W = 62
\n" ); document.write( "2W + 30 + 2W = 62
\n" ); document.write( "4W + 30 = 62
\n" ); document.write( "4W = 32
\n" ); document.write( "W = 8 inches
\n" ); document.write( "Choice C.
