Question

A high school track is shaped as a rectangle with a half circle on either side.

96 m
35 m
Jake plans on running four laps. How many meters will Jake run? Use 3.14 for s.
O 301.9 m
O 823.6 m
1,207.6 m
O 1,647.2 m
How many meters will jake run?

Answer 1

1,207.6 C

Explanation:

got it right took the quiz

Answer 2

1,207.6 m

Explanation:

The picture of the question in the attached figure

we know that

The perimeter of the high school track is equal to the sum of the length of rectangle multiplied by 2 plus the circumference of a circle (remember that the sum of the circumference of two semicircles is equal to the circumference of one circle)

so

`P=2L+\pi D`

we have

`L=96\ m\\D=35\ m`

substitute

`P=2(96)+(3.14)(35)=302.9\m`

Multiply the perimeter by 4 (because Jake plans on running four laps)

so

`302.9(4)=1,207.6\ m`
