# Construct a 2 ×3

Answer :

Let A = [aij]2×3

So, the elements in a 2×3 matrix are

a11, a12, a13, a21, a22, a23

A = ………………. (1)

a11 = 2×1 – 1 = 2 – 1 = 1 a12 = 2×1 – 2 = 2 – 2 = 0 a13 = 2×1 – 3 = 2 – 3 = – 1

a21 = 2×2 – 1 = 4 – 1 = 3 a22 = 2×2 – 2 = 4 – 2 = 2 a23 = 2×2 – 3 = 4 – 3 = 1

So, from (1)
