We can apply that idea to fractions, too, but it is a little different in the sense that now think of the whole side of the rectangle as being 1 whole, the other side also is 1 whole, and the whole rectangle also illustrates 1 whole in terms of area. The fractions being multiplied represent length of the sides, whereas the result fraction represents area.

P.S. ....
| Check out these short video clips from my favorite band - Rockabilly.US. They play oldies, Elvis, country, and top hits of the 50s and 60s. It's a show with large band, costumes, choreography, little skits, "Kid Kritters", 6 dancing/singing girls, junior dancer troupe, etc. | |
|
"Be My Baby" originally by the Ronettes |
Impossible Dream (Elvis song) |
| Most importantly, the band wants to use the uplifting and energetic music to bring some fun, happiness and encouragement into people's lives. They're doing it selflessly to help others, and don't get paid for any of it themselves. And I admire that! | |
