# The perimeter of a square with a side of 9.65 cm is equal to the perimeter of a rectangle

The perimeter of a square with a side of 9.65 cm is equal to the perimeter of a rectangle with a width of 8.7 cm. Find the length of the rectangle.

1) First, we find the perimeter of this square. It is known that the perimeter is the sum of the lengths of all sides. So, to find the perimeter of a given square, you need to multiply this side of the square by 4, since all sides of a square are equal.

The perimeter of this square = 4 * 9.65 cm = 38.6 cm.

2) It is known that the perimeter of this square is equal to the perimeter of a rectangle whose width is 8.7.

3) So, we will find the length of the given rectangle.

17.4 + 2 * length = 38.6;

2 * length = 21.2;

length = 10.6.

Answer: The length of the rectangle is 10.6 cm.
