Abigail is making a rectangular collage. She has 54 square photographs. Each photograph is 1 inch by 1 inch. She wants to make the collage 9 inches long (or 9 photographs long).
Rectangular collage with one side labeled 9 inches
How wide can Abigail make her collage if she wants to use all of her photographs?
divide 54 inches by 9 inches which would be 6 inches therefore she would have to make her collage 6 inches wide to fit all of her photographs. (to check this, all you have to do is multiply 9 by 6, then you get 54, which proves that this is correct.)
