Given,

  • Side of the octagon = ( 2a + 1 ) units

» Perimeter means total length of its boundary.

→ Octagon has 8 sides.

So,

→ Perimeter of Octagon = Length of 8 sides

→ Perimeter of Octagon = 8 ( 2a + 1 ) units

→ Perimeter of Octagon = 16a + 8 units

Therefore,

  • Perimeter of the octagon is [tex] \bf 16a + 8 [/tex] units.
