I have no idea about how to prove this statement hence require a proof. The only definition I have is that rank is the highest order square submatrix of a matrix which has non-zero determinant.Our professor has given the statement in question as a definition without any prrof hence asking for help.Thanks!

Why is the number of non zero rows in row echelon form of the matrix the rank of the matrix
