The measures of the sides of a triangle are shown as polynomials. The measures are: 2s^3 + 4; 5s; 4s^2 + 1. Write a polynomial to represent the perimeter of the triangle.

Answer 1

Perimeter
= 2s^3+4 + 5s + 4s^2 + 1
= 2s^3 + 4s^2 + 5s + 5

Why was this question difficult for you?
If you are given the three sides of a triangle, wouldn't you just add them up to find the perimeter ?

Answer 2

Isn't the formula for a triangle A=1/2bh? Do we use the formula for this question or-
