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?

1 answer

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.
