Perimeter of a Square

The perimeter of a square is the sum of the lengths of all its sides. In this case, the perimeter of the square is given as 8 cm.

To find the perimeter of the rectangle formed by combining three of these squares, we need to determine the dimensions of the rectangle.

Dimensions of the Rectangle

Since three squares are combined to form the rectangle, we can assume that the rectangle is made up of three rows of squares.

Let's denote the side length of each square as s. Since the perimeter of each square is 8 cm, we can write the equation:

4s = 8

Simplifying the equation, we find that the side length of each square is 2 cm.

Since there are three squares in each row, the length of the rectangle will be 3 times the side length of the square, which is 6 cm. The width of the rectangle will be equal to the side length of the square, which is 2 cm.

Perimeter of the Rectangle

To find the perimeter of the rectangle, we add up the lengths of all its sides.

The length of the rectangle is 6 cm and the width is 2 cm. Therefore, the perimeter of the rectangle is:

2(6 + 2) = 2(8) = 16 cm

So, the perimeter of the rectangle formed by combining three squares with a side length of 8 cm each is 16 cm.
