**a) **The x-**coordinate** of the **center of gravity** is .

**b) **The y-**coordinate** of the **center of gravity** is .

<h3>Determination of the coordinates of the center of gravity</h3>

Let suppose that each **square** has an <em>uniform</em> **density**, the **coordinates** of the **center of gravity** of each **square** with respect to the **origin** are, respectively:

The **center of gravity** of the <em>entire</em> **system** is found by applying definition of <em>weighted</em> **averages**:

Where , , and are weights of the each square, in newtons.

Now we proceed the coordinates of the center of gravity of the entire system:

**a)** The x-**coordinate** of the **center of gravity** is .

**b)** The y-**coordinate** of the **center of gravity** is .
