The length of one side of the rectangle is 6 cm, the other is 2 cm less, find the pyrimeter of this rectangle.

Initially, we will calculate the width of this rectangle if we subtract only 2 cm from its length.
1) 6 cm – 2 cm = 4 cm – is the length of the rectangle.
Next, we define the perimeter of the rectangle by adding together two identical sides of the length and two identical sides of the width of this figure.
P = 6 cm + 6 cm + 4 cm + 4 cm = 12 cm + 8 cm = 20 cm.
Bottom line: the perimeter of the rectangle is 20 cm.
