Question

The perimeter of a triangle is 5a – 2b + 4. The sum of two sides of it is a – b. Find its third side.

Answer 1

Answer:

As we know that the perimeter of a triangle is sum of length of all the sides. Hence,

Perimeter =2a+3b+b−a+4a−2b

⇒5a+2b

....

Answer 2

Answer:

4a-2b+4

Step-by-step explanation:

if perimeter = 5a-2b+4

then,third side=5a-2b+4-(a-b)

5a-3b+4-a+b

4a-2b+4,third side
