The perimeter of the sector is 27.2cm.
A sector is a portion of a circle bounded by an arc and two radii.
Analysis:
Perimeter of a sector = ∅/360 x 2πr + 2r
where r = radius of circle = 7cm , ∅ = angle subtended by the arc at the center = 108°.
Perimeter of sector = 108/360 x 2 x 22/7 x 7 +2 x 7 = 27.2cm
