Two identical squares were used to make a rectangle with sides of 3 cm 1 cm 5 mm. Express the lengths of the sides of a rectangle in millimeters and subtract the perimeter of this rectangle and each square.

Let’s translate the lengths of the sides of the rectangle in millimeters.

3 cm = 30 mm.

1 cm 5 mm = 15 mm.

Since the rectangle consists of two squares, the side of the square is 30/2 = 15 mm.

We calculate the perimeter of the rectangle: Ppr = 2 * (15 + 30) = 90 mm.

Determine the perimeter of the square: Ркв = 4 * 15 = 60 mm.

Answer: The perimeter of the rectangle is 90 mm, the perimeter of the square is 60 mm.
