B. 2×2×5×11=220
if you divid 220 by 2=110
110÷2=55, 55÷5=11, 11÷11=1
2, 2,5, 11
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

Let's say that BC is x, so that AB is 4x, and AE = y.
The shaded area then is represented by 4xy/2 = 2xy.
The total area is represented by (4x+x)*y = 5xy.
The fraction of these is 2xy/5xy = 2/5.
