Question

Find the perimeter of the figure given to the right. Use the approximation 3.14

Answer 1

To answer this question we will use the following diagram as a reference:

Notice that the perimeter of the given figure is the sum of 2 times the perimeter of the semicircles and 48m, the perimeter of each semicircle is:

`\begin{gathered} P_S=\pi* radius=6\pi m \\ \approx18.84m. \end{gathered}`

Therefore the perimeter of the given figure is:

`P=2*18.84m+48m=85.68m.`

Answer: 85.68m.
