Draw a rectangle that has the same perimeter as a square with a side of 4 cm to indicate the length

Draw a rectangle that has the same perimeter as a square with a side of 4 cm to indicate the length and width of the rectangle.

According to the condition, there is a square with a side of 4 cm, you need to draw a rectangle with the same perimeter as the square, designate the length and width.
The perimeter of this square is equal to the sum of the lengths of all 4 sides, that is, 4 + 4 + 4 + 4 = 16 cm, which means that the perimeter of the rectangle is also 16 cm.
Let the length of the rectangle be X cm and the width Y cm, so 2X + 2Y = 16, and X + Y = 8.
The length of the rectangle is greater than the width, which means X = 5 cm, and Y = 8 – 5 = 3 cm.
You need to draw a rectangle that is 5 cm long and 3 cm wide.
