document.write( "Question 1168984: The Pinetown Recreation Bureau planned to build a rectangular ice-skating rink with dimensions 40m by 70m. Their budget has been cut, so they must reduce the area of the rink by 650 sq. meters. A strip will be removed from one end, and a strip of the same width will be removed from one side. Find the width of strips. \n" ); document.write( "
