To find the perimeter of this rectangular shape, we only need to find two values:
These values are 10 - 6 = 4, and 15 - 4 = 11
Then, the perimeter of this figure is 10m + 11m + 6m + 4m + 4m + 15m = 50m.
The total area is the area of the blue rectangle and of the small red square:
[tex]A_1=11\cdot10=110m^2,A_2=4\cdot4=16m^2\Rightarrow A_1+A_2=110m+16m^2=126m^2[/tex]
Then, the area is 126m^2.
In summary, the area of the figure is 126m^2 and the perimeter is 50m.
