Find the squares of the following numbers using column method. Verify the result by finding the square using the usual multiplication:

(i) 25

(ii) 37

(iii) 54

(iv) 71

(v) 96

(i) 25

Here, a = 2, b = 5

25² = 625

And,

25² = 25× 25 = 625

(ii) 37

Here, a = 3, b = 7

37² = 1369

And,

37² = 37× 37 = 1369

(iii) 54

Here, a = 5, b = 4

54² = 2916

And,

54² = 54× 54 = 2916

(iv) 71

Here, a = 7, b = 1

71² = 4941

And,

71² = 71× 71 = 4941

(v) 96

Here, a = 9, b = 6

96² = 9216

And,

96² = 96× 96 = 9216
