The width of a rectangle is 5 ft. less than the length. The area of the rectangle is 176 ft.2 Find the width and length of the rectangle. Formula: Area = Length Width\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "let the length of the rectangle be x\r
\n" ); document.write( "\n" ); document.write( "the width will be 5 less = x-5\r
\n" ); document.write( "\n" ); document.write( "The area of a rectanle = L * W\r
\n" ); document.write( "\n" ); document.write( "x*(x-5) = 176\r
\n" ); document.write( "\n" ); document.write( "x^2-5x-176=0\r
\n" ); document.write( "\n" ); document.write( "x^2-16x+11x-176=0\r
\n" ); document.write( "\n" ); document.write( "x(x-16)+11(x-16)=0\r
\n" ); document.write( "\n" ); document.write( "(x-16)(x+11)=0\r
\n" ); document.write( "\n" ); document.write( "x=16 or x= -11\r
\n" ); document.write( "\n" ); document.write( "x=16 is positive \r
\n" ); document.write( "\n" ); document.write( "so length = 16 feet \n" ); document.write( "

\n" );
