Answer:
38 [tex]ft^{2}[/tex]
Step-by-step explanation:
We can see this figure as
WHOLE RECTANGLE - PORTION OF RECTANGLE CUT OUT
We know area of a rectangle is length * width
If this was the WHOLE RECTANGLE, the area would have been:
5 * 10 = 50 sq. ft.
The portion cut out is also a rectangle with dimensions:
Length = 6
Width = 5 - 3 = 2
Thus,
Area = 6 * 2 = 12 sq. ft.
So, the area of the figure is 50 - 12 = 38 sq. ft.
