Answer: 170 meters.

Step-by-step explanation:

1. The formula for calculate the perimeter of a rectangle is:

$P=2l+2w$

Where $l$ is the lenght and $w$ is the width.

2. You must solve for the lenght.

3. The problem gives the perimeter and the width, then, when you substitute these values you obtain the following result:

$2l=P-2w\\l=\frac{P-2w}{2}\\l=\frac{940m-2(300m)}{2}\\l=170m$
