Answer:
L= 12170 ft
Explanation:
The runaway at the airport has the shape of a rectangle and the area of 2,312,300 ft². The rectangular runaway is 190 ft wide . The length is what we are asked to find.
area of a rectangle = LW
Where
L = length
W = width
area of a rectangle = LW
area of the rectangular runaway = 2,312,300 ft²
W = 190 ft
L = ?
2,312,300 = L × 190
2,312,300 = 190L
divide both sides by 190
L = 2,312,300/190
L= 12170 ft
