Draw a square ABCD with side AB equal to 3cm6mm. Calculate its area and perimeter.

Therefore, we need to draw a square shape, all sides of which are 3 cm 6 mm, since all sides of a square are the same.

Let’s calculate the perimeter of a square by adding together all its four identical sides:

P = 3 cm 6 mm + 3 cm 6 mm + 3 cm 6 mm + 3 cm 6 mm = 6 cm 12 mm + 6 cm 12 mm = 12 cm 24 mm = 14 cm 4 mm.

Next, we calculate the area of a rectangular shape by multiplying two sides:

S square = 3cm 6mm * 3cm 6mm = 3.6cm * 3.6cm = 12.96cm2.

Bottom line: the perimeter of the square is 14.4 cm, and its area is 12.96 cm2.
