(1) Area of the ΔDEI=1/2 × Base × Height
⇒1/2×60×40
=1200m

(2) Area of the Trapezium EFGI=1/2× (Sum of the two parallel sides) × Height
⇒1/2×(60+50)×70
⇒1/2×110×70
=3850m

(3) Area of the ΔAFG=1/2 × Base × Height
⇒1/2×50×50
=1250m

(4) Area of the TrapeziumABCH=1/2 ×(Sum of the two parallel sides) × Height
⇒1/2×(40+30)×80
⇒1/2×70×80
=2800sqm
(5) Area of theΔCDH= 1/2× Base × Height
The height of this figure is not clear in the image. I think it is 80m and I have assumed it 80m.
⇒1/2×40×80
=1600m

Total area = Area of ΔDEI+ Area of the Trapezium EFGI+ Area of ΔAFG+ Area of Trapezium ABCH+ Area of ΔCDH
⇒1200+3850+1250+2800+1600
=10700 m

So, the area of the figure ABCDEF is 10700m
