To find the area of Alfredo's scale drawing, we need to consider the scale factor used to create the drawing. If the length of the top edge in the scale drawing is 6 inches, and the actual length of the top edge on the poster is 18 inches, then the scale factor is 6/18 = 1/3.
Since the area of a rectangle is calculated by multiplying the length by the width, we need to apply the scale factor to both dimensions of the original poster to find the dimensions of Alfredo's scale drawing.
The original poster dimensions are given as 18 inches by 12 inches. Applying the scale factor of 1/3, we find that Alfredo's scale drawing dimensions are 6 inches by 4 inches.
Therefore, the area of Alfredo's scale drawing is 6 inches x 4 inches = 24 square inches.
