The perimeter of the square is 36 cm. One of the sides of the rectangle is simultaneously the side of the square

The perimeter of the square is 36 cm. One of the sides of the rectangle is simultaneously the side of the square, and the second side of the same rectangle is one third of this length. Calculated the area of the rectangle.

1. We calculate the length of the side of the square:

36: 4 = 9 centimeters.

2. The length of one of the sides of the rectangle is also 9 centimeters, since by condition

the problem is the side of the square.

3. Calculate the length of the other side of the rectangle:

9 x 1/3 = 3 centimeters.

4. Calculate the area of the rectangle:

9 x 3 = 27 cm ^ 2.

Answer: the area of the rectangle is 27 cm ^ 2.
