B) Dark spots appearing from time to time on the sun's surface >> Sunspots

C) Brief eruptions of intense high-energy radiation from the sun's surface >>  Solar flares

D) The rise of hotter, less dense fluid and the sinking of cooler, denser fluid >> Convection

Area of the rectangle = ( x²+12x+27)unit²

Step-by-step explanation: Length = x+3  Breadth = x+9

∴ Area of Rectangle = L×B

(x+3)(x+9) = x²+9x+3x+27 = (x²+12x+27) unit²
