Answer:
Step-by-step explanation:
In trapezium TSRQ
The formula for area is 1/2×base×sum of two parallel sides
Therefore,area=1/2(18)(20+25)
=405cm^2
In triangle TPQ
Area = 1/2×base×height
Therefore, area= 1/2×25×10
=125cm^2
Area of polygon=area of the trapezium+area of the triangle
=405+125
=530cm^2
