In the given figure, a square of side 1 cm is joined to a square of side 3 cm. The perimeter of the new figure is:
According to the question,
The overlapping side of the two squares will not be considered in the perimeter value of the new figure. Only the outer boundaries should be considered.
Therefore, the perimeter of the new figure= 1 cm + 1 cm + 1 cm + 2 cm + 3 cm + 3 cm + 3 cm = 14 cm
