A cylindrical metal specimen having an original diameter of $12\mathrm{.}8mm$ and gauge length of

$50\mathrm{.}80mm$ is pulled in tension until fracture occurs. The diameter at the point of fracture is

$),$ and the fractured gauge length is $72\mathrm{.}14mm.$ Calculate the ductility in

terms of percent reduction in area and percent elongation.
