Hope it helps!! Mark this answer as brainliest if u found it useful and follow me for quick and accurate answers...

Step-by-step explanation:

First Join Point P and S

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

Area of square of side 20m=  

Height for triangle =30-20=10m

base is as same as QR=20m

Area of triangle:

$\frac{1}{2} \times b \times h \\\\= \frac{1}{2} \times 20\times 10\\\\=100m^{2}$

Total area = $(400+100)m^2$ = $500m^2$  ---> Answer
