Explanation: The reason for this is that a conic projection is good for lay out of a globe but for acurate viewings it’s the worst and the Mercator projection although is the most common projection it strechs the size of things for example you could say Greenland is around the size of africa but in reality it’s 14 times smaller Therefore the Equal-area projection is the best.
