Think about the graph of the system. A big part of answering is finding the line containing point (-4,-2) which is perpendicular to the given line 3x+4y-5=0. The distance from the point of intersection of the two lines to the point (-4,-2) is the length of the radius of the circle centered there; and knowing this radius, you can find the area of the circle.
