Question

Verify the identity (a+b) whole square geometrically by taking a=2units b=4units

Answer 1

see a2 means a square and similarly b2 is b square

(a+b)2=(a+b) * (a+b)
= a2+ab+ba+b2.
=a2+b2+2ab

Answer 2

Given:- a=2
b=4

(a+b)²=a²+b²+2ab

taking LHS,

(a+b)²
=(2+4)²
=(6)²
=36

now taking RHS,

a²+b²+2ab
=(2)²+(4)²+2×2×4
=4+16+16
=36

hence,
LHS = RHS

verified.
