Question

The sides of a triangle are ( 4a + 3b) , (-5a-8b), (7a +6b). Find the perimeter of the traingle .​

Answer 1

Answer:

Step-by-step explanation:

Sides of the triangle : (4a + 3b), (-5a - 8b), (7a + 6b)

Perimeter = Sum of all sides

                 = (4a + 3b) + (-5a - 8b) + (7a + 6b)

                 = 4a + 3b - 5a - 8b + 7a + 6b

                 = 4a - 5a + 7a + 3b - 8b + 6b

                 = (6a - b) units
