Question

Write an expression for the perimeter of the triangle in simplest form.

Answer 1

Perimeter of any triangle is:

`\text{Perimeter}=\text{length of first side +length of second side + length of third side}`

In right angle triangle is length of sides is x, x+5, x-3.

Then the perimeter is:

`\begin{gathered} \text{perimeter}=x+x+5+x-3 \\ =3x+5-3 \\ =3x+2 \end{gathered}`
