-----------------
17*40 = 680 sq inches
------
If 1.5" is add to each side, --> 20*40 = 800 sq inches
----
(800 - 680)/680 = 14/68
14*100/68 =~ 20.59% increase
==============
If it's added to the 40 inches also, you'll have to clarifiy that or calculate it as above.

The dimensions will become
+17+%2B+2%2A1.5+ by +40+%2B+2%2A1.5+ or
+20+ by +43+
+A%5B2%5D+=+20%2A43+%0D%0A%7B%7B%7B+A%5B2%5D+=+860+ in2
The original area was:
+A%5B1%5D+=+17%2A40+
+A%5B1%5D+=+680+
+A%5B2%5D+-+A%5B1%5D+=+860+-+680+
+A%5B2%5D+-+A%5B1%5D+=+180+ in2
The area is increased by 180 in2
