Answer 2

Answer:

$\small\underline\mathrm\purple {perimeter= \: 2(l + b) }$

$\small\underline\mathrm\pink { \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =2(40 + 15) }$

$\small\underline\mathrm\purple { \: \: \: \: \: \: \: \: \: \: \: \: \: \: \ \: \: \: \: \: \: \: \: \: \: \: \: 2 \times 55}$

$\small\underline\mathrm\purple { \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =110cm}$
