A training field is formed by joining a rectangle and two semicircles, as shown below. The rectangle is 80 m long and 63 m wide. What is the length of a training track running around the field? (Use the value 3.14 for pie, and do not round your answer. Be sure to include the correct unit in your answer.)

Respuesta :

The semi-circles form an entire circle with diameter 74.  The radius is 37

 The area of the rectangle is 95 x 74 = 7030

The area of the circle is 3.142 x 37*37 = 4298.66

The total area is 11328.66
