Question

The three sides of a triangle arerepresented by 4m + 3, 8m - 4,and 2m + 5. Write and simplify anexpression to represent theperimeter of the triangle.

Answer 1

The sides given are 4m + 3, 8m - 4, and 2m + 5.

The perimeter is the sum of the sides by definition so it follows:

`\begin{gathered} P=4m+3+8m-4+2m+5 \\ P=14m+4 \end{gathered}`

Hence the perimeter is 14m+4.
