Calculate the perimeter of a rectangle with sides of 4 cm and 5 cm and draw a segment whose length is 3 times less than the perimeter of this rectangle.
The perimeter of a rectangle is found using the following formula:
P = 2 * (a + b), where a and b are the length and width of the rectangle.
Let’s find the perimeter according to the available data:
P = 2 * (4 + 5) = 2 * 9 = 18 cm.
The length of the segment to be drawn will be equal to:
18: 3 = 6 cm.
