Question

What is the area of a square of side (a-b) cm?

Answer 1

Step-by-step explanation:

Area of the square of side= (a-b)  

                                             =a²-2ab+b²                                                                

Answer 2

$\textbf{\large{Answer -}}$

Given, side of the square is $(a-b)$ cm.

We know that,

Area of square = ${side}^{2}$

==> ${(a-b)}^{2}$

==> ${a}^{2} + {b}^{2} - 2ab$

So the area of a square of side $(a-b)$ will be $\boxed{{a}^{2} + {b}^{2} - 2ab}$
