Answer:
Total perimeter=19+13+34=66 m
Thus total area
=90+4-24
=70 m²
Step-by-step explanation:
A- PERIMETER
As per marking in the image:
1.Perimeter from A to F
=9+4+2+2+2=19 m
2.F to H : 4+9=13 m
3. H to A =(6*4)+(2*5)=24+10=34m
Thus Total perimeter=19+13+34=66 m
*****************************************************
B- AREA:
1. ar( ABGH) =AB *BG=9*(BC+DE+FG)
=9*(4+2+4)=9*10=90 m²
2. ar( CDEF) = CD*DE=2*2=4 m²
Less
3. ar(IKNM) +ar(OPRQ)
=6*2+6*2=24
Thus total area
=90+4-24
=70 m²
