Question

Find the perimeter of a triangle that has the side lengths given below.6cm, 7 Square root of 3, square root of 27

Answer 1

$6+10\sqrt{3}\quad$

1) Since Perimeter is by definition the sum of all side lengths of a polygon, we can write out the following:

$\begin{gathered} 6,7\sqrt{3},\sqrt{27} \\ P=6+7\sqrt{3}+3\sqrt{3} \\ P=6+10\sqrt{3}\quad \end{gathered}$

2) Note that we could simplify the square root of 27.
