Question

Find the perimeter of the triangle (Simplify your answer. Type an exact answer, using radicals as needed.)

Answer 1

Given:

The side of the triangle are

`\begin{gathered} a=5√(125)in \\ \\ b=4√(180)in \\ \\ c=√(147)in \end{gathered}`

Required:

To find the perimeter of the triangle.

Step-by-step explanation:

The formula for perimeter is

`P=a+b+c`

Here

`\begin{gathered} P=5√(125)+4√(180)+√(147) \\ \\ =5√(25*5)+4√(9*20)+√(49*3) \\ \\ =5*5√(5)+4*3√(20)+7√(3) \\ \\ =25√(5)+12√(20)+7√(3) \end{gathered}`
