Answer:
76.5in²
Step-by-step explanation:
First we will find the area of the square. This is done by multiplying the side length (9in) by itself.
The area of the square is 81in².
Next we will find the area of the triangular hole. We can use the formula , where b is the base of the triangle (3) and h is the height of the triangle (3).
The area of the triangle is 4.5in².
Now we can find the area of the figure by subtracting the area of the square and the area of the triangular hole.
The area of the figure is 76.5in².
That is the answer
