Step-by-step explanation:

(1.1m- 0.4) (1.1m +0.4)​

Using identity (a+b)(a-b) = a^2 - b^2

(1.1m- 0.4) (1.1m +0.4)​  = (1.1m)^2 - (0.4)^2

(1.1m- 0.4) (1.1m +0.4)​  = 1.21m^2 - 0.16

$\sf \boxed {\blue{(1.1m - 0.4) \: (1.1m + 0.4)}}$

$\sf \implies(1.1m + 0.4)^{2}$

$\sf \implies(1.1m) ^{2} - (0.1) ^{2}$

$\sf \green{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: using \: identity II}$

$\sf \implies {\boxed {\orange{1.21m ^{2} - 0.16}}}$
