Square is figure whose all dimensions are same.** Centroid of square** lies where, diagonals intersects each other. As shown in the figure.

**Example**

Find the centroid of square whose breadth and thickness is 5 ft.

**Solution**

Centroid of square lies where, diagonals intersect each other.

Draw a vertical line from the midpoint of reference y-axis & in the same way draw a horizontal line from the midpoint of reference x-axis. Centroid lies at a point where horizontal and vertical lines intersect. As shown below.

From figure, it can be seen that centroid of square is at 2.5′ from reference x and y-axis.
