Question

A training field is designed by joining two semicircles and a rectangle. The rectangle is 91 m long and 69 m wide. What is the length of a training track around the field?

Answer 1

The length around it is

(two lengths of the rectangle) + (2 halves of the circle)

= (182 meters) + (the circumference of one full circle)

The circumference of a circle is (pi) x (diameter).

Notice that the width of the rectangle is also the diameter of the circle.
