c) An equilateral triangle of side 3cm d) A square of side 3cm.​

Answer 1

Answer:

a) Regular pentagon of side 3cm

Answer 2

Answer:

Regular hexagon of 3 cm

Step-by-step explanation:

It is because,

side =3cm.

(a)A pentagon has 5 sides

So, (5×3)cm

=15cm

(b)A regular hexagon has 6 sides

So,(6×3)cm

=18cm

(c)An equilateral triangle has 3 sides

So, (3×3)cm

=8cm

(d)A square has 4 sides

So,(3×4)cm

=12cm

Since, 15 is less than 18 and 8 is less than 18 and 12 is less than 18.

So, the answer is (d).

I hope it may help you.
