We have to determine
What is the area of this figure?
How to determine the area of the figure?
The area of the complex figure is determined in the three steps than adding all areas to get the area of the hole figure.
The area of the given figure is determined by the following formula;
[tex]\rm Area = length \times width[/tex]
The width of the first part is 3 km and the length is 4km.
[tex]\rm Area = length \times width\\\\Area = 3 \times 4\\\\Area = 12[/tex]
The width of the second part is = 3+ 9 = 12 km
And the length of the second part is 6 km.
[tex]\rm Area = length \times width\\\\Area = 12 \times 6\\\\Area = 72[/tex]
The width of the third part is = 3+ 9 + 5 = 17 km
And the length of the third part is 7 km.
[tex]\rm Area = length \times width\\\\Area = 17 \times 7\\\\Area = 117[/tex]
Therefore,
The area of the given figure is;
= 12 + 72 + 117 = 203
Hence, the area of the figure is 203 square km.
