Answer:
15x + 28
Step-by-step explanation:
Given, in the figure,
Sides of the triangle are = 5x+10, 5x+10 and 5x+8
As we know,
Perimeter of a triangle = Sum of the three sides
Therefore,
Perimeter of the given triangle
= (5x+10) + (5x+10) + (5x+8)
- [Opening the brackets and bringing like terms together]
= 5x + 5x + 5x + 10 + 10 + 8
= 15x + 28
Hence, 15x + 28 is the simplified answer.
