Question

Find the perimeter of a triangle whose sides are 2a +3b,b-a, 4a-2b.​

Answer 1

Answer:

5a+2b

Step-by-step explanation:

• The perimeter is the sum of the sides of the polygon.
• Here, the sides are (2a+3b), (b-a) and (4a-2b).
• Adding the sides:

1. (2a+3b)+(b-a)+(4a-2b)
2. 2a+3b+b-a+4a-2b
3. 2a-a+4a+3b+b-2b
4. 2a+4a-a+3b+b-2b
5. 5a+2b

So, the perimeter of this triangle is 5a+2b.

Answer 2

Answer:

5a+b

Step-by-step explanation:

2a+3b,b-a,4a-3b. perimeter = sum of all sides

=2a-a+4b+3b+b-3b

=5a+b

Hence, perimeter = 5a+b
