Given that the midpoint of triangle is (0,0),(3,0),(0,4).then join these points we get a traingle and find the slopes of the lines joint these points we  get 0/-3,4/0,-4/3.now the lines joing these points are parallel to the third side of the original triangle.then find the equation of the original triangle we get y=4,x=3&4x+3y=0.finding out the point of these lines we get the vertices of the original triangle i.e. (3,-4),(3,4),(-3,4). finding the area by taking determinant of these points we get 24 sq.units
