The area is the length times the width. So if the width of the original rectangle is W and the length is L, then the width of the new rectangle is .9W and the length of the new rectangle is 1.3L. Therefore the area of the new rectangle is (1.3L)(.9W) = 1.17LW. The area is increased by a factor of 1.17.
