Question

Q.12. Perimeter of pentagon with each side 3 cm =________

(a) 12

(b) 18

(C) 16

(d) 15

​

Answer 1

Given :

• Each side of Pentagon is given 3 cm

To find :

• The Perimeter of the Pentagon

Solution :

We have to find the Perimeter of the Pentagon by using the formula it also has given the side of the Pentagon which is 3cm So let's solve!

${ \underline{ \underline{ \mathfrak{ \green{As \: we \: know \: that}}}}}$

$\;\boxed{\sf{\purple{Perimeter_{\:(pentagon)} = 5 \times side}}}$

$: \implies$ Side $\leadsto$ $\sf{3_{\:(cm)}}$

$: \implies$ 5 $\times$ $\sf{3_{\:(cm)}}$

$: \implies$ ${\underline{\underline{\boxed{\pink{\mathfrak{15 \ cm}}}}}}$

•°• Hence, verified! that the Perimeter of the Pentagon is $\sf{15_{\:(cm)}}$ which means Option $\sf\purple{(d)}$ is correct
