Alex has a small notebook that is shaped like a rectangle. She knows one side is 6 cm and another side is 4 cm. Explain how to find the distance around the notebook without using a ruler.

Respuesta :

6+6+4+4
Add all of the side lengths together.

Answer : The distance around the notebook is, 20 cm

Step-by-step explanation :

Given:

Length of rectangle = 6 cm

Breadth of rectangle = 4 cm

As we know that perimeter (distance) is the sum of all side of a given figure.

As there are 4 sides of rectangle.

Perimeter of rectangle = 2(Length + Breadth)

Perimeter of rectangle = 2(6 cm + 4 cm)

Perimeter of rectangle = 2(10 cm)

Perimeter of rectangle = 20 cm

Therefore, the distance around the notebook is, 20 cm
