Area is length times width.
You have area, 1,813,500 and width 150.
1,813,500=L*150
L=1,813,500/150
12090 feet

The area of a rectangle is
+A+=+h%2Aw+
where +A+ = area in ft2
+h+ = height in ft
+w+ = width in ft
-------------------
I'll call the length of the runway +h+, so
The area of the runway is +A+, so
+A+=+1813500+ ft
The width of the runway is:
+w+=+150+ ft
------------------
+A+=+h%2Aw+
+1813500+=+h%2A150+
Divide both sides by +150+
+h+=+1813500%2F150+
+h+=+12090+ ft
The length of the runway is 12,090 ft
