Answer:
[tex]40\ ft^{2}[/tex]
Step-by-step explanation:
we know that
To find out how many square feet of exterior carpet we will need for this hole, subtract the area of the two interior rectangles from the area of the full green rectangle.
so
Area of the full green rectangle
[tex]A=12*4=48\ ft^{2}[/tex]
Area of the two interior rectangles
[tex]A=3*2+1*2=8\ ft^{2}[/tex]
Find the area of outdoor carpet
[tex]A=48-8=40\ ft^{2}[/tex]
