The ratio of L:W = 9:4. \n" ); document.write( "L = 9x \n" ); document.write( "W = 4x \n" ); document.write( ". \n" ); document.write( "Perimeter = 104 cm \n" ); document.write( "P = 9x + 4x + 9x + 4x \n" ); document.write( "26x = 104 \n" ); document.write( "x = 4 \n" ); document.write( ". \n" ); document.write( "L = 9*4 = 36 cm \n" ); document.write( "W = 4*4 = 16 cm \n" ); document.write( ". \n" ); document.write( "Check the perimeter. \n" ); document.write( ". \n" ); document.write( "2(36) + 2(16) = 72 + 32 = 104 \n" ); document.write( ". \n" ); document.write( "Re-read the question to determine if you've answered it. \n" ); document.write( "Nope. It asks for the area of the rectangle. \n" ); document.write( ". \n" ); document.write( "Answer: Area = L*W = 36*16 = 576 cm^2 \n" ); document.write( ". \n" ); document.write( "Done. \n" ); document.write( " |
