Let x be the length of the side on the original square. Then 2x is the length on the larger one
\n" ); document.write( "\"AreaOfSquare+=+Side%5E2\"
\n" ); document.write( "\"AreaOfOriginalSquare+=+x%5E2\"
\n" ); document.write( "\"AreaOfBigSqaure+=+%282x%29%5E2+=+4x%5E2\"
\n" ); document.write( "So the bigger square has 4 times the area of the original one
