We can use the scale factor to find the length of the left edge in the scale drawing:
scale factor = length in scale drawing / original length
In this case, the scale factor is:
8 / 24 = 1/3
So the length of the left edge in the scale drawing is:
36 * 1/3 = 12
Now we can find the area of the scale drawing:
Area = length x width
Area = 12 x 8
Area = 96 square inches
Therefore, the area of Alfredo's scale drawing is 96 square inches.
