Given:-

An reatacngle with a half sphere at one side.

To find:-

The perimeter of the given image.

Now we are going to find the perimeter of the half sphere. The formula to find half sphere is,

$\pi r+d$

Where r is radius and d is diameter.

The radius of the sphere is 2.5 and the diameter is 5. Substituing the values we get,

$\begin{gathered} \pi r+d=3.14*2.5+5 \\ \text{ =12.85} \\ \text{ =12.9} \end{gathered}$

Now we find the perimeter of the rectangle below. we get,

$5+5+5=15_{}$

Now to get the total perimeter we need to add both the values. so we get,

So the required perimeter is 27.9
