Question

Find the perimeter of a pentagon with a side of length 12in.

Answer

To find the perimeter of a pentagon, we will use the following formula:

$P = 5 \cdot a$

where a is the length of one side of the pentagon.

Now, we know the length of one side of the pentagon is 12in.

Knowing this, we can substitute into the formula. We get

$P = 5 \cdot 12\text{in}$

$P = 60\text{in}$

Question

Find the perimeter of a pentagon with a side having a length of 21in.

Answer

A pentagon has 5 sides. To find the perimeter, we will use the following formula:

where a is the length of a side of the pentagon.

Now, we know the length of a side of the pentagon is 21in.

Knowing this, we will substitute into the formula. We get

Question

Find the perimeter of a pentagon with a side having a length of 15cm.

Answer

To find the perimeter of a pentagon, we will use the following formula:

$P = 5 \cdot a$

where a is the length of one side of the pentagon. Because a pentagon has 5 equal sides, we can use any side in the formula.

So, we know the length of one side of the pentagon is 15cm. So, we can substitute. We get

$P = 5 \cdot 15\text{cm}$

$P = 75\text{cm}$
