Final answer:
To find the total area of the 12 airport runway threshold markings in square meters, we first convert the length and width from feet to meters, then calculate the area for one stripe, and finally multiply it by 12 to get the total area, which is approximately 961.6028 m².
Step-by-step explanation:
To calculate the total area in square meters of the 12 threshold markings on an airport runway, we need to first find the area of one marking and then multiply by the number of markings. The area of one marking is found by multiplying its length and width. Given that each marking is 150 feet long and 5.75 feet wide, we first convert the dimensions to meters, knowing that 1 foot equals 0.3048 meters.
Area of one marking in meters = (150 feet × 0.3048 meters/foot) × (5.75 feet × 0.3048 meters/foot)
= (45.72 meters) × (1.7526 meters)
= approximately 80.1669 m2
To find the total area for all 12 markings we multiply the area of one marking by 12:
Total area for 12 markings = 80.1669 m2 × 12
= 961.6028 m2
