The field inside a running track is made of a rectangle that is 84.39 m long and 73 m wide to gether with a half circle at each end. what is the distance around the track?

398.21 m

Step-by-step explanation:

The field inside a running track is made of a rectangle that is 84.39 m long and 73 m wide to gather with a half circle at each end.

So, the radius of each half circle will be m.

Therefore, the total distance around the track i.e perimeter of the area covered by the track will be = 2 × Perimeter of each half circle + 2 × Length of the rectangle.

= Perimeter of full circle + 2 × Length of the rectangle.

=

=

= 398.21 m.(Answer)

Step-by-step explanation:

39 cars every 3 hrsthat means (39/3) = 13 cars every hr

and if its 13 cars every hrin 7 hrs, there will be (7 * 13) = 91 cars <==

you can either do it that waythe unit rate way...OR

you can set it up as a proportion...

39 cars to 3 hrs = x cars to 7 hrs...

39 / 3 = x / 7cross multiply

(3)(x)= (39)(7)

3x = 273

x = 273/3

x = 91 <

either way, u get the correct answer
