# If the length L of a rectangle is 3 meters more than twice its width and its perimeter is 300 meters, which of the following equations could be used to find L?

##### 1 Answer

#### Answer:

#### Explanation:

You have two equations to work with, the equation that describes the perimeter of the rectangle and the equation that describes the relationship between its length,

The perimeter of a reactangle is always equal to

In your case, you have

Now, you know that if you **double** the width and **add** three meters to the result, you get

You now have a system of two equations

Use the value of

This means that

The rectangle will thus be **49 m** wide and **101 m** long.
