The longest runway at an airport has the shape of a rectangle and an area of 2 comma 312 comma 300 square feet. This runway is 190 feet wide. How long is the runway?

L= 12170  ft

Step-by-step 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

answer:

the answer is b) divide by -4 on each side and flip the sign.

step-by-step explanation:

we first need to start by dividing. this is because it is a multiplication problem to start.

we also need to make sure we flip the sign because any time you multiply or divide by negative numbers, the sign must be flipped.
