The field inside a running track is made up of rectangles that is 84.39 meters long and 73 M wide together with a half circle and east side what is the distance around the inside of the track explain or show your reasons

The field inside a running track is made up of a rectangle 84.39 m long and 73 m wide, together with a half circle at each end. The running lanes are 9.76 wide all the way around. What is the area of the running track that goes around the field? Show your work.

Area of the running track is 4187.87 m^2

Step-by-step explanation:

Given:

Inner rectangle:

Length of the rectangle = 84.39 m

Width of the rectangle = 73 m

Radius of the inner semicircle = 36.5 m

Outer rectangle:

Length of the rectangle = (73+9.76+9.76) = 92.52 m

Width of the rectangle = 84.39 m

Radius of the outer semicircle = 46.26 m

We have to find the area of the running track.

Note:

Two semicircles with same radius makes a circle.

Area of the running track = ar (outer track) - ar (inner track)

Area of the track consist of one rectangle area along with 2 semicircles area  (or a circles area).

⇒ Area of the running track :

⇒ ar (outer track) - ar (inner track)

⇒

⇒

⇒

⇒

⇒

The area of the running track that goes around the field is 4187.87 m^2

8

Step-by-step explanation:

it would be 8 as 17 is on the y axis and then you go along the corridor and down the stairs and the dot is on 8
