Question

The longest runway at an airport has the shape of a rectangle and an area of 1,934,400 square feet. This runway is 160 feet wide. How long is the​ runway?

Answer 1

The length of the runway = 12090 feet

Explanation:

The formula involving the area of a rectangle is

`A=wl`

here

• 'w' is the width

• 'l' is the length

Given

Area A = 1,934,400 square feet

Width w = 160 w

Length l = ?

Using the formula

`A=wl`

substituting the values

1,934,400 = 160 × l

l = 1,934,400 / 160

l = 12090 feet

Therefore, the length of the runway = 12090 feet
