The perimeter of a rectangle is the sum of the length and width of the rectangle multiplied by two.

The perimeter of a rectangle can be the same for rectangles that have different values ​​for the length and width of the rectangle.

1). Find the number of different rectangles with a perimeter of 24 centimeters.

a) The sides of the rectangle are 1 cm and 11 cm.The perimeter is (1 + 11) * 2 = 24 cm.

b) 2 cm and 10 cm.Perimeter = (2 + 10) * 2 = 24 cm.

c) 3 cm. and 9 cm. Perimeter = (3 + 9) * 2 = 24 cm.

d) 4 cm. and 8 cm. Perimeter = (4 + 8) * 2 = 24 cm.

e) 5 cm and 7 cm.The perimeter is (5 + 7) * 2 = 24 cm.

f) 6 cm and 6 cm. Perimeter = (6 + 6) * 2 = 24 cm.
