Original Poster Scale Drawing

left edge (in.) 36 ?
top edge (in.) 24 8

A local food organization puts out a healthy food poster. The poster is in the shape of a rectangle, and its dimensions are given in the table. Alfredo wants to make a smaller version of the poster to hang up in the community center. He makes a scale drawing of the poster with the length of the top edge given in the table. What is the area of Alfredo’s scale drawing?

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.
