Question

Use the applet to give the square a side length of 1.3 cm. At this moment, what is the measure of the perimeter of the square (in cm) in units of the side length of the square (in cm)

Answer 1

Perimeter, P = 5.2 cm

Explanation:

Perimeter is the sum of all the sides.

All sides of a square is equal. Here, the side of a square is 1.3 cm.

The perimeter of a square is given by :

P = 4 × side

It means,

P = 4 (1.3 cm)

P = 5.2 cm

Hence, the perimeter of the square is 5.2 cm.
