A rectangle does not have a diameter but it has diagonals.
So using Pythagoras' theorem each diagonal is about 351.141mm in length rounded to 3 decimal places.
80mm x 120mm equates to 3.15 inches x 4.72 inches.
A rectangle does not have a diameter, as such, but the diagonal is similar enough. If the sides of a rectangle are x cm and y cm then, using Pythagoras's theorem, the diagonal is sqrt(x2 + y2) cm.
Do you mean perimeter? If so....2 x length + 2 x width.

140 x 120 x 4 = 67200mm3
120 squared = 120 x 120 = 14400

You need two measurements for a rectangle: length x width. If both are equal, you should say so (in this case, it is a square).
Divide the surface area by the circumference of the circle, which is a product of the diameter x Pi. Essentially, an unrolled cylinder is a rectangle.
