hi
Step-by-step explanation:
firstly we must divide the shape like this
and the area of first rectangular is 27 m²( 9m × 3m)
then second rectangular's area is 48m²( 12m × 4m and we found 4m from 9-5)
the third rectangular's area is 10 m² ( we found it from 9-4)
Total is 27+48+10=85 m²
hope it helps
have a nice day
