I have a piece of paper sized 10 cm bye 10 cm by 10 cm by 10 cm. I fold it in half to make a rectangle. I fold it in half again to make a much smaller square. What is the perimeter of the rectangle? What is the perimeter of the smaller square?

The perimeter of the rectangle is 30cm and the perimeter of the square is 20cm

Step-by-step explanation:

Given

Dimension of Paper = 10 cm by 10 cm

Required

Find the perimeter of the shapes formed when the paper is folded

The dimension of the paper shows that it is a square;

At the initial stage when it's folded in half to form a rectangle;

This implies that only one side of the paper is folded and the new dimension becomes 10cm/2 by 10cm

New Dimension = 10cm/2 by 10cm

New Dimension = 5cm by 10cm

The perimeter of this is calculated as follows;

Perimeter = 2(L + B) where L and B are the dimensions of the rectangle

Perimeter = 2(5cm + 10cm)

Perimeter = 2(15cm)

Perimeter = 2 * 15cm

Perimeter = 30cm

When the paper is further folded in half to form a square;

This implies that the other side that wasn't folded initially, is now folded;

The new dimension becomes 5cm by 10cm/2

New Dimension = 5cm by 10cm/2

New Dimension = 5cm by 5cm

The perimeter of this is calculated as follows;

Perimeter = 2(L + L) where L is dimensions of the square

Perimeter = 2(5cm + %cm)

Perimeter = 2(10cm)

Perimeter = 2 * 10cm

Perimeter = 20cm

Hence, the perimeter of the rectangle is 30cm and the perimeter of the square is 20cm
