A training field is formed by joining a rectangle and two semicircles, as shown below. The rectangle is 91 m long and 55 m wide. What is the length of a training track running around the field? (Use the value 3.14 for it, and do not round your answer. Be sure to include the correct unit in your answer.)​

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

1. perpendicular

2. parallel

3. perpendicular

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
