Question

Find the area of each of the following fields in the figure. All dimensions are in meters

Answer 1

Area of $△DEI$ = $\frac{1}{2}\times EI\times DI=\frac{1}{2}\times 60\times 40=1200m^2$

Area of $△$$DHC$= $\frac{1}{2}\times HC\times DH=\frac{1}{2}\times 40\times 80=1600m^2$

Area of trapezium $ABCH$ $=$ $\frac{1}{2}(CH+AB)\times HA$

$=$ $\frac{1}{2}(40+30)\times 70$

$=2450m^2$

Area of $△$$AGF$= $\frac{1}{2}\times AG\times GH=\frac{1}{2}\times 50\times 50=1250m^2$

Area of trapezium $EFGI$$=$ $\frac{1}{2}(EI+FG)\times IG=\frac{1}{2}\times (60+50)\times 70=3850{cm}^2$
