The length of the walkway is 2 feet more than the width. What is the perimeter of the walkway \n" ); document.write( "---------------------- \n" ); document.write( "Let the width be \"x\"; length = \"x+2\". \n" ); document.write( "---- \n" ); document.write( "Area = x(x+2) = 63 \n" ); document.write( "x^2 + 2x - 63 = 0 \n" ); document.write( "(x+9)(x-7) = 0 \n" ); document.write( "Positive solution: \n" ); document.write( "x = 7 ft. (width) \n" ); document.write( "x+2 = 9 ft. (length) \n" ); document.write( "----------------------- \n" ); document.write( "Perimeter = 2(length + width) \n" ); document.write( "P = 2(9+7) = 2(16) \n" ); document.write( "P = 32 ft. \n" ); document.write( "========================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
