An ant stands at one vertex of a rectangular sheet of paper. The ant then proceeds to walk all the way around the perimeter of the paper. The dimensions of the sheet of paper are 358 inches by 278 inches. How many inches does the ant travel? Show your work.
The perimeter of a rectangle is equal to the sum of the four sides. In this case, the dimensions of the rectangle are 358 inches by 278 inches, so the ant has to travel a distance of $358\text{ in.} + 278\text{ in.} + 358\text{ in.} + 278\text{ in.} = \boxed{1272\text{ in.}}$.
