asha plans to place vacation photos of her friends on a square bulletin board mesuring 72 units by 72 units.
A) which size of photo can be placed without any spaces or overlapping? show your work.

1) 8by 10 2) 6 by 4 3) 5 by 7

B) how many photos of that size can be placed on the bulletin board?



Answer :

The answer is 2.... The 6x4 photo because that's the only one with common factors so there won't be any empty space at the end.

As far as how many... find the area of both and divide:

6x4=24
72x72=5184
5184/24= 216 photos
