$A_{fig.}=2A_{ABCDEFGHIJ}+A_{ABCP}+2A_{IJKL} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: </p><p>+A_{MNGH}+2A_{BCDE}+2A_{HILM} \\ \: \: \: \: \: \: \: \: \: \: = 2(33) + (8 \times 10) + 2(10 \times 1.5) \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: + (10 \times 5) + 2(6 \times 10) + 2(10 \times 3) \\ \: \: \: \: \: \: \: \: \: \: = 66+ 80 + 30 + 50 + 120 + 60 \\ \: \: \: \: \: \: \: \: \: \: = \boxed{\huge\red{406}}\: cm{}^{2} \\ \: \: now \: \\ </p><p>\rightarrow A_{ABCDEFGHIJ} = A_{ABEJ} - A_{H GFI} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = (6 \times 8) - (5 \times 3) \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 48 - 15 = 33$
