Definition: Two rectangles are similar if their sides are in the same ratio.

You need to convert the units:

1 foot = 12 inches

dimensions of poster:

5 feet long = 5*12 = 60 inches 

3.5 feet wide = 3.5 * 12 = 42 inches

Ratio of the poster: 60/42 = 30/21

Ratio of the painting: 30/21

They have the same ratio, so the poster is similar to the original painting.
