The sides of the rectangle are 6 and 3 cm. It is necessary to build a square with a perimeter 3 times smaller

The sides of the rectangle are 6 and 3 cm. It is necessary to build a square with a perimeter 3 times smaller than that of the rectangle. How many cm will be the side of this square.

1) Find the perimeter of the rectangle using information about its length (6 centimeters) and width (3 centimeters).

(6 + 3) * 2 = 9 * 2 = 18.

The perimeter of the rectangle is 18 centimeters.

2) Determine the perimeter of the square.

18/3 = 6.

The perimeter of the square is 6 centimeters.

3) Find out the length of each side of the square by composing and solving an equation, where x will be one of its sides.

x * 4 = 6;

x = 6/4;

x = 1.5.

The length of each side of the square is 1.5 centimeters.

Answer: you need to build a square, each side of which is 1.5 centimeters.
