Donald is making a paper crown at his little sister's princess birthday party. He tapes together 2 pieces of construction paper that are each 200 millimeters long. When he tries on the crown, he realizes that it's too small. So, he adds one more piece of construction paper. How many centimeters long is Donald's paper crown now?

Respuesta :

Answer:

Step-by-step explanation:

First, let's find the total length of the paper crown after Donald adds one more piece of construction paper.

Each piece of construction paper is 200 millimeters long. Since Donald adds one more piece, the total length of the crown is:

Total length = 2 pieces * 200 millimeters/piece + 1 piece * 200 millimeters/piece

             = (2 * 200) + (1 * 200) millimeters

             = 400 + 200 millimeters

             = 600 millimeters

Now, let's convert this length to centimeters, as 1 centimeter is equal to 10 millimeters:

600 millimeters / 10 = 60 centimeters

So, Donald's paper crown is now 60 centimeters long.
