Hi,
Note: begin by noting that the resulting square will have 1/2 of the area that the rectangle had.
.
Let x be the length of the side of the resulting square when the rectange is folded in half.
.
x%5E2+=+%281%2F2%29%2A338
.
x%5E2+=+169
x = 13 in
.
26in would be the length of the longer side of that rectangle
