Julian has an image that measures 12"x18" in size. He knows that he will need background support that is approximately the same size as his image and that his overmat will need an additional three inches on all sides. Based on this, what size overmat will Julian need?
18 X 24
24X32
16X18
12X18
To calculate the size of the overmat, we need to add 3 inches to each dimension of the image.
The image is 12" x 18". Adding 3 inches to each dimension gives us 12 + 3 = 15 inches for the width, and 18 + 3 = 21 inches for the height.
Therefore, Julian will need an overmat that is 15" x 21" in size.
