The vertices of the triangle are (1,2),(h,-3) and(-4,k). I f the centroid of the triangle is at the point (5,-1) then find the value of h+k2+h+3k2

The vertices of the triangle are (1,2),(h,-3) and(-4,k). I f the centroid of the triangle is at the point (5,-1) then find the value of $\sqrt{{(h + k)}^{2} + {(h + 3 k)}^{2}}$
