An athletic field is a 42 yd-by-84 yd rectangle, with a semicircle at each of the short sides. A running track
20 yd wide surrounds the field. If the track is divided into eight lanes of equal width, with lane 1 being the
inner-most and lane 8 being the outer-most lane, what is the distance around the track along the inside
edge of each lane?

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
