How to Add Polynomials to Find Perimeter
To find the perimeter of a shape whose sides are polynomials, add all the side expressions together and combine like terms. The perimeter is still just the total distance around, but the answer comes out as an expression rather than a number.
Adding Polynomials to Find Perimeter -Example 2
The perimeter of the shape is the sum of the sides. So,
Perimeter(=(2x-1)+(3x)+(5x)+(4x-2)=2x-1+3x+5x+4x-2)
Group and add like terms,
Perimeter(=(2x+3x+5x+4x)+(-1-2)=14x-3)
