Solution

The correct option is C 8.4 cm
A Perimeter is the boundary of any closed geometrical figure.

The perimeter of the given figure is the sum of arc length BC and the slant lengths AB and AC.

Arc is semicircle so its perimeter is $π r$

Perimeter $= π r + 2 \times$ Slant height

$= \frac{22}{7} \times 1.4 + 2 \times 2$

$\Rightarrow 4.4 + 4 = 8.4 c m$
