Question

A training field is formed by joining a rectangle and two semicircle, as shown below. The rectangle is 100 m long and 7 m wide. What is the length of the training track running around ( use the 3.14 for pie , and do not round your answer)

Answer 1

The answer will be the sum of the longer sides of the rectangle plus the perimeter of the full circumferencem then:

`2(100)+2\pi(35)=200+70\pi=200+70(3.14)=419.8`

then the answer will be

`419.8\text{ m}`
