There is a proportional relationship between the size of a projected image on a screen and the distance of the screen from the projector. An image that is projected onto a screen 10 feet away is a rectangle with dimensions of 2 feet by 3 feet. If the screen is moved to a distance of 15 feet from the projector,

Q: what will be the dimensions of the larger image projected onto the screen?

i want to see how you solve this one too..do i set up a proportion??
