Question

# The perimeter of the notebook is ______ cm.

- 60
- 30
- 15
- 90

Hint:

### Polygon is a two- dimensional closed figure which is consist of three or more-line segments. Each polygon has different properties. One of the polygons is quadrilateral. Quadrilateral is a four-sided polygon with four angles and the sum of all angles of a quadrilateral is . Here, we have to find the perimeter of the given quadrilateral using the properties of the quadrilateral.

## The correct answer is: 90

### In the question there is a notebook whose length is 30 cm and breadth is 15 cm.

Here, we have to find the perimeter of the notebook.

As it is shown in the figure above, we can say that the opposite sides of the notebook are equal.

So, the notebook is rectangular shaped.

So, the perimeter of notebook = 2 ( Length + Breadth )

= 2(30 + 15)

= 90 cm

Thus, the perimeter of the notebook is 90 cm.

Therefore, the correct option is d, i.e., 90 cm.
