  2. 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.
