The distance around a two-dimensional shape, or the sum of all of its sides.

Ki tāu titiro, he roa ake te paenga o te tapawhā hāngai, tērā i te paenga o te porowhita?

Tuhia tētahi tapawhā hāngai, kia 16cm tōna paenga, engari kia rahi rawa atu te horahanga e taea ana.

Ko te paenga o tēnei tapawhā: 3cm + 4cm + 4cm + 6cm = 17cm

Ko te ture hei tātai i te paenga o te porowhita: P = πwh
(P = paenga, π = 3.14 ... (tētahi tau pūmau), wh = whitianga)
