Column I|Column II The length of the common chord of two circles of radii 3 units and 4 units which intersect orthogonally is `k/5` . Then `k` is equal to|p. 1 The circumference of the circle `x^2+y^2+4x+12 y+p=0` is bisected by the circle `x^2+y^2-2x+8y-q=0.` Then `p+q` is equal to|q. 24 The number of distinct chords of the circle `2x(x-sqrt(2))+y(2y-1)=0` , where the chords are passing through the point `(sqrt(2),1/2)` and are bisected on the x-axis, is|r. 32 One of the diameters of the circle circumscribing the rectangle `A B C D` is `4y=x+7.` If `Aa n dB` are the poinst `(-3,4)` and (5, 4), respectively, then the area of the rectangle is|s. 36
