Answer»

Step-by-step explanation:

(a+b)

2

≡a

2

+2ab+b

2

Draw a square with side a+b ie 3+2

LHS AREA of whole square

=(3+2)

2

=5

2

=25

RHS = Area of square with side 3 units + Area of square with side 3 units + Area of RECTANGLE with side 3,2 units + Area of rectangle with side 2,3 units

=3

2

+2

2

+3×2+3×2

=9+4+6+6=25

LHS=RHS.

Hence VERIFIED
