Finding the Perimeter of Peter's Rectangle

To find the perimeter of Peter's rectangle, we can use the information provided about the squares he cut from it. Let's calculate the perimeter step by step.

1. Identify the Sizes of the Squares: - Peter cut the rectangle into two large squares, three smaller squares, and five tiny squares. - The large squares have a side length of 10 cm. - The smaller squares have a side length smaller than 10 cm, and the tiny squares have an even smaller side length.

2. Calculate the Side Length of the Original Rectangle: - Since Peter cut the rectangle into two large squares, the side length of the original rectangle must be twice the side length of the large squares, which is 20 cm.

3. Determine the Perimeter of the Rectangle: - The perimeter of a rectangle is calculated using the formula: P = 2*(length + width). - In this case, the length and width of the rectangle are 20 cm and 10 cm, respectively. - Therefore, the perimeter P = 2*(20 + 10) = 2*30 = 60 cm.

So, the correct answer for the perimeter of Peter's rectangle is 60 cm. Therefore, among the options provided, the correct answer is not listed.
