\"A pasture is twice as long as it is wide. Its area is 115,200 ft square. How wide is the pasture?\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = width
\n" ); document.write( "2x = length {it is twice as long as it is wide}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Area of a rectangle = length x width\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x(2x) = 115,200 {substituted into area formula}
\n" ); document.write( "2x^2 = 115,200 {multiplied x by 2x and added exponents}
\n" ); document.write( "x^2 = 57,600 {divided both sides by 2}
\n" ); document.write( "x = 240 {took square root of both sides}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "width = 240 ft
