Question

A training field is formed by joining a rectangle and two semicircles, as shown below.

Answer 1

354.98 meters.

Explanation:

To find the length of the training track running round the field, we find the perimeter of the field.

• Each of the semicircular part has a ,diameter of 57m,.

First, we find the perimeter of the two semicircles.

For a semicircle with a diameter, d, its perimeter is calculated using the formula:

`Perimeter=(\pi d)/(2)`

Therefore, the perimeter of the two semicircular part of the track is:

`\begin{gathered} P=2*(\pi d)/(2) \\ =3.14*57 \\ =178.98\;m \end{gathered}`

Next, add the two lengths of the rectangle:

`\begin{gathered} \text{ Length of the training track}=178.98+2(88) \\ =178.98+176 \\ =354.98\;m \end{gathered}`

The length of the training track is 354.98 meters.
