How to Add Polynomials to Find Perimeter

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\(=(2x+3x+5x+4x)+(-1-2)=14x-3\)

Exercises for Add Polynomials to Find Perimeter
