Consider a block matrix A = [A11 A12 A13; A21 A22 A23] where A11 is a 5 x 2 matrix, A22 is a 3 x 4 matrix, and A23 is a 3 x 5 matrix. Find the dimensions of each block given. A12 is a _ x _ matrix. A13 is a _ x _ matrix. A21 is a _ x _ matrix.

(f) If A is a 4 x 3 matrix, then det(54) = 5 det A. (g) If A is a 3 x 3 matrix, then det(5A) = 1125 det A. (h) If A is an n x n matrix containing columns consisting of zeroes only, then det A = 0.
