Answer 2

Hello Dear!!!

Here's your answer....

(4.8)^2+ 2* 4.8 * 0.2 + (0.2)^2

We can do this sum by multiplication...and then addition...

But it will be a long process...

So..there's a formula

Your question is in the form of a formula

The formula is

(a)^2 + 2ab + (b)^2 = (a+b)^2

Let's apply the formula

(4.8)^2+ 2* 4.8 * 0.2 + (0.2)^2

Here

a is 4.8

b is 0.2

so....

(4.8 + 0.2)^2

(5)^2

25..

25 is the answer.....
