Answer 2

Concept:

A square number:

It refers to a number or integer when it is multiplied by itself once.

Given:

We are given a number:

135.

Find:

We need to find the square of it by diagonal method.

Solution:

WE need to find:

135²

First of all, we will find the square of 5 that is:

5² = 25

Now, we will multiply 13 by its successor that is 13 + 1 = 14. WE get that:

13 × 14 = 182

And now, we will write the answer of second step first and then the first step to obtain the square of 135.

= 18225

135² = 18225

Therefore, we get that the square of 135 is 18225.
