To find the area of Alfredo's scale drawing, we need to determine the scaled dimensions based on the information provided in the table.
The original dimensions of the poster are:
- Left edge: 36 inches
- Top edge: 24 inches
The scale drawing has the top edge of 8 inches. To find the scale factor, we can compare the scaled top edge to the original top edge:
\[ \text{Scale factor} = \frac{\text{Scaled top edge}}{\text{Original top edge}} = \frac{8 \text{ inches}}{24 \text{ inches}} = \frac{1}{3} \]
Now, we can apply this scale factor to find the scaled left edge:
\[ \text{Scaled left edge} = \text{Original left edge} \times \text{Scale factor} = 36 \text{ inches} \times \frac{1}{3} = 12 \text{ inches} \]
With the dimensions of the scale drawing being:
- Scaled left edge: 12 inches
- Scaled top edge: 8 inches
We can now calculate the area of the scale drawing:
\[ \text{Area} = \text{Scaled left edge} \times \text{Scaled top edge} = 12 \text{ inches} \times 8 \text{ inches} = 96 \text{ square inches} \]
Therefore, the area of Alfredo’s scale drawing is:
96 square inches.
