Given:

There are given the scalene triangle.

where,

The perimeter of is 14.5 cm.

Explanation:

To find the equation, we need to use the formula of perimeter:

So,

From the formula of perimeter:

[tex]P=a+b+c[/tex]

Now,

According to the question:

It has been said that the longest side is twice that of the shortest side.

So,

Let's assume that a is the longest side and b is the shortest side.

So,

The equation for the shortest side is:

[tex]\begin{gathered} 6.2=2c \\ c=3.1 \end{gathered}[/tex]

Then,

Put the value of perimeter, a and c into the given perimeter formula:

So,

[tex]\begin{gathered} P=a+b+c \\ 14.5=6.2+3.1+b \\ 9.3+b=14.5 \end{gathered}[/tex]

Final answer:

Hence, the correct option is B.
