Question

Find the area of the polygon from the figure give below:
With solution...

Answer 1

First Join Point P and S

Now AREA of polygon=Area of square PQRS+Area of Triangle PTS

Area of square of side 20m=
${20}^{2} = 400 {m}^{2}$
Height for triangle =30-20=10m
base is as same as QR=20m

$area \: of \: triangle = \frac{1}{2} \times 20 \times 10 \\ 100 {m}^{2}$
Total area=(400+100)m^2
