Let m⃗\vec{m} be a vector of magnitude 3\sqrt{3} and perpendicular to the vectors i^+j^\hat{i} + \hat{j} and j^−k^\hat{j} - \hat{k}. Let n⃗\vec{n} be another vector of magnitude 262\sqrt{6} and perpendicular to the vectors 2i^−j^2\hat{i} - \hat{j} and j^+2k^\hat{j} + 2\hat{k}. The area (in sq. units) of the triangle formed with m⃗\vec{m} and n⃗\vec{n} as sides is
