A training held is formed by joining a rectangle and two semicircles, as shown below. The rectangle is 83 m long and 63 m wide. What is the length of a training track running around the field? (Use the value 3.14 for 7t, and do not round your answer. Be sure to include the correct unit in your answer.)

its b

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
