Detailed Solution

It is required to find the square of the number 28.
Now divide the provided number into two equal parts, one of which must be a multiple of 10, and the other must not.
⇒28 = 20 + 8
Squaring the number,
⇒ (28) 2 = 20+8 2 ⇒ 20+8 20+8 ⇒20 20+8 +8 20+8 ⇒400+160+160+64 ⇒784  
The number 784 is therefore the square of 28.
Therefore, option 2 is correct.
