625 sq feet.
The maximum area possible using 100 feet of fencing is that inside a circular fence. But, since you asked about a rectangular fence: a 25x25 fence would hold 625 square feet. a 10x40 fence would hold 400 square feet. a 5x45 fence would hold 225 square feet. As you can see, the square is the rectangle that encompasses the largest area, as it is closest to a circle.
For the same base dimensions (base area) and the same height, the rectangular prism has more surface area.
Given the surface area of a rectangular prism, there are infinitely many rectangular prisms possible.
The formula for finding the surface area of a rectangular prism is 2(wh + lw + lh), where w is width, h is height, and l is length. 3.14 is the value for pi, which is only used for circular objects, like circles, cylinders, and spheres. It has nothing to do with rectangular prisms. Click on the related link below for an illustration of the formula for the surface area of a rectangular prism.

A = area, L = length, W = width A = LW L = 2W A = (2W)W = 2W2 2W2 = 50 W = 5 ft
Let the length be 2x and the width be x: length*width = area 2x*x = 50 2x2 = 50 x2 = 25 x = 5 feet
