Answer 2

`1,207.6\ m`

Explanation:

step 1

Find the perimeter of one lap

we know that

The perimeter of one lap is equal to the circumference of a complete circle (two half circles is equal to one circle) plus two times the length of 96 meters

so

`P=\pi D+2(96)`

we have

`D=35\ m`

`\pi =3.14`

substitute

`P=(3.14)(35)+2(96)`

`P=301.9\ m`

step 2

Find the total meters of four laps

Multiply the perimeter of one lap by four

`P=301.9(4)=1,207.6\ m`
