Answer:
23380 m²
Step-by-step explanation:
here in the given figre following shapes are there
- triangleEDQ
- trapaziumQPBD
- trianglePBA
- triangleARC
- triangleECR
now area of the polygon = area of triangleEDQ+area of trapaziumQPBD+area of trianglePBA+area of triangleARC +area of triangle ECR
now we will go step by step
- area of triangle EDQ
area of triangle =1/2*base *height
=1/2*100*100
=5000m²
- area of trapazium QPBD
area of trapazium=1/2*[sumof parallel side]*height
= 1/2*[100+50]*110
=8250m²
- area of triangle PBA [now we are direct evaluting the values as we know the formula]
area of triangle = 1/2*50*50
=1250 m²
- area of triangle ARC
=1/2*120*[30+50+50]
=1/2*120*130
=7800 m²
- area of triangle ERC
=1/2*120*[100+80]
=1/2*120*180
=1080 m²
now adding all the values as
=5000+8250+1250+1080+7800
=23380m²
∴the area of polygon is 23380 m²
