Answer 1

Answer:

1480000m²

Step-by-step explanation:

area of triABI = 1/2×1800×600

=540000m²

area of tri BIC = 1/2×1200×600

=360000m²

area of tri AFG=1/2×800×200

=80000m²

area of □ HECD=1/2(100+300)1000

=200000m²

area of □GFHE=1/2(200+300)1200

=300000m²

now______

area of whole ABCDEF = area of tri ABI+area of tri BIC + area of tri AFG+ area of □HECD+area of □GFHE

=540000+360000+8000+200000+300000=1480000m²✔✔✔✔
