Answer
When a rectangle is folded in half along its length then its length is reduced to half, but the width stays the same.
As,
Area = length × width
Even though the length is halved, the width is unchanged so the new area will be half of the original area i.e.,
Original area = 16 cm2
New area = × 16 cm2 = 8 cm2
