To determine the scale factor used when a photo is tripled in size, you need to compare the dimensions of the original photo to those of the enlarged photo.

In this case, the original photo measures 3 inches by 5 inches. To triple its size, each dimension (length and width) is multiplied by a factor of 3.

So, the dimensions of the enlarged photo would be:

Length = 3 inches x 3 = 9 inches
Width = 5 inches x 3 = 15 inches

The original photo was scaled up by a factor of 3 in both dimensions. Therefore, the scale factor used to triple the size of the photo is 3.
