\n" ); document.write( "Find the side \"highlight_green%28x%29\"of a square room such that if its length and its width are each increased by 4 meters,
\n" ); document.write( "the area is increased by 120 square meters. Note: Area of the Square is x^2
\n" ); document.write( "(x+4)(x+4) = x^2 + 120
\n" ); document.write( " x^2 + 8x + 16 = x^2 + 120
\n" ); document.write( " 8x = 104
\n" ); document.write( " x = 13
\n" ); document.write( "CHECKING our answer***
\n" ); document.write( " 17^2 = 169 + 120 = 289
