Following figures are formed by joining six unit squares. Which figure has the smallest perimeter in Fig. 6.4?
For First figure:
Perimeter = Total number of sides × length of each side
= 10 × 1
= 10 cm
For second figure:
Perimeter = Total number of sides × length of each side
= 12 × 1
= 12 cm
For third figure:
Perimeter = Total number of sides × length of each side
= 14 × 1
= 14 cm
For fourth figure:
Perimeter = Total number of sides × length of each side
= 14 × 1
= 14 cm
So correct answer is D [i].
