GPT-4o mini · Answer

To determine the size of the overmat Julian will need, we start with the dimensions of his image, which are 12” x 18”. Since the overmat needs to be an additional three inches on all sides, we need to add 6 inches to each dimension (3 inches for each side).

Calculating the dimensions for the overmat:

Width: 12” + 6” = 18”
Height: 18” + 6” = 24”

So, the size of the overmat will be 18” x 24”.

Given the available response options, the correct answer is:

at least 18”x24”.
