we have `A=[{:(a,1,x),(2,sqrt(3),x^(2)-y),(0,5,(-2)/(5)):}]`
(i) the order of matrix A=`3xx3`
(ii) the number of elements `=3xx3=9`
[since the number of elements in an `mxxn` matrix will be equal to `mxxn=mn`]
(iii) `a_(23)=x^(2)-y,a_(31)=0,a_(12)=1`
[since , we know that `a` is a representation of element lying in the row and column]
