Answer 1

Step-by-step explanation:

$perimeter \: of \: rectangle \: (1) = 2(l + b) \\ 2(8 + 1) \\ 2 \times 9 = 18 cm \\ breadth \: of \: rectangle \: (2) = 3 + 3+ b = 8 \\ 6b = 8 \\ b = 8 - 6 \\ b = 2cm\\ perimeter \: of \: rectangle \: (2) = 2(l + b) \\ 2(3 + 2) \\ 2 \times 5 \\ 10cm \\ total \: perimeter = 18cm + 10cm \\ 28cm$
