Question

The perimeter of the given figure is ___ ${cm}^2$

Answer 1

A Perimeter is the boundary of any closed geometrical figure.

A 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 $\pi r$

$Perimeter=\pi r+2\times Slantheight$
$=\frac{22}{7}\times 1.4+2\times 2$

$\Rightarrow 4.4+4=8.4cm$
