Answer 2

Answer:

ΔABK = $750 m^2$

ΔAGJ = $1,400 m^2$

Trapezium BCIK = $2,100 m^2$

Trapezium FGJH = $\frac{1}{2}$ $. (20+40) . 80$ $m^2$ = $2,400 m^2$

ΔEFH = $400 m^2$

Trapezium CDEI = $3,600 m^2$

Step-by-step explanation:

ΔABK = $\frac{1}{2}$ $. 30 . 50$ $m^2$ = $750 m^2$

Let's name the point J on Straight line AIHE, so that GJ is perpendicular to AJIHE.

ΔAGJ = $\frac{1}{2}$ $. 40 . 70$ $m^2$ = $1,400 m^2$

Trapezium BCIK = $\frac{1}{2}$ $. (30+40) . 60$ $m^2$ = $2,100 m^2$

Trapezium FGJH = $\frac{1}{2}$ $. (20+40) . 80$ $m^2$ = $2,400 m^2$

ΔEFH = $\frac{1}{2}$ $. 40 . 20$ $m^2$ = $400 m^2$

Trapezium CDEI = $\frac{1}{2}$ $. (50+40) . 80$ $m^2$ = $3,600 m^2$
