Answer
To find the ratio of the width to the length of the raised runway, we first identify the width as 4 feet. The length can be derived from the provided information. Using the ratio,

Answer
Given the length of the floor runway is 54 feet, we convert this to metres using the provided conversion factor:
ext{Length in metres} = rac{54 ext{ feet}}{3.28084} egin{aligned}= 16,459199... ext{ m} ext{ (approximately)} \\ ext{So,} ext{ the length of the floor runway is } 16,46 ext{ m.} \\ ext{} \\ ext{} \\ ext{(rounded to two decimal places)} \\ ext{} \\ 16,46 ext{ m} ext{ (rounded using decimal places.)} ext{ } \\ ext{} \\ ext{ } ext{ 16.46 m.}

Answer
4.1.3 (a) The second- and third-row seats are not arranged exactly behind the first-row seats as this arrangement mitigates obstruction caused by the first-row spectators.
4.1.3 (b) There is a gap between the two runways to allow for safe passage of people and to avoid potential collisions.

Answer
The radius of the round table is found by dividing the diameter by 2:
ext{Radius} = rac{1,828 ext{ m}}{2} = 0,914 ext{ m}
Then, substituting the radius in the area formula:
extArea=3,142imes(0,914)2=2,627112extm2.

Answer
First, calculate the circumference of the round table:
extCircumference=3,142imes1,828=5,7460896extm.
Then, to find the maximum length allocated to each person seated around the round table:
ext{Length per person} = rac{5,7460896 ext{ m}}{10} = 0,57460896 ext{ m}.
