Perimeter = 100 + 69 + 100 + 69 = 338 metres.
If you use the IRB pitch size requirements the the calculation is 100mtrs x 2 length plus 70mtrs x 2 wide plus 22mtrs (in goal) x 2 Total 384 metres
Its the sam size as your standard picth!
A rugby pitch shall be no longer than 100 meters by 70 meters wide A Gaelic football pitch is Length - 130m minimum and 145 maximum Width - 80m minimum and 90 maximum
The rugby pitch is slightly larger. An American football field, including the end zones, is 120 yards long (109.7 meters) and 53.3 yards wide (48.7 meters). The field must conform to those measurements. The rugby pitch, in comparison, can vary in size, but the playing area must not exceed 100 meters in depth and 70 meters in width, and the dimensions are expected to conform with these measurements as closely as possible. The try zones must not exceed 22 meters each in depth nor be shallower than 10 meters, "where practicable." So a rugby pitch generally spans from 130 to 144 meters long and 70 meters wide.
