विकल्प
उत्तर
Explanation:
(i) 
Let the square `square` = 1 unit
Then, perimeter = Sum of all sides
= 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1
= 10 units
(ii) 
Perimeter = Sum of all sides
= 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1
= 12 units
(iii) 
Perimeter = Sum of all sides
= 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1
= 14 units
(iv) 
Perimeter = Sum of all sides
= 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1
= 14 units
Hence, smallest perimeter = 10 units
Which is the perimeter of figure (i).
