The area of a square quilt is 196 square inches. There is a smaller square patch on the quilt with an area of 49 square inches.

Makovka662 [10]

To find your answer you would find the perimeter of the small square which is 28.

You would then find the perimeter of the big square which is 56.

Next, you subtract 56 from 28 and get 28.

So the difference is 28 inches.

Hope this helps!!
