Let's begin by identifying key information given to us:
The shape is a composite shape composed of one square & 4 semi-circles
However, to obtain the perimeter of the shape, we will sum the perimeter of all 4 semi-circles
The perimeter or circumference is therefore calculated as shown below:
[tex]\begin{gathered} C(semi-circle)=\pi r \\ r=5 \\ \pi=3.14 \\ C(semi-circle)=3.14\times5=15.7 \\ \text{The circumference for 4 semi-circles is given as:} \\ C_{total}=4\times15.7=62.8 \\ \therefore C_{total}=62.8unit^2 \end{gathered}[/tex]
