Answer:
[tex]12x^2+8x+25[/tex]
Step-by-step explanation:
Given
From Figure
Sides of Triangle
[tex]8x^2 \\4x^2+15\\8x+10[/tex]
Now, using concept
Perimeter of triangle = Sum of the sides of triangle
So,
Perimeter of triangle = [tex]8x^2+4x^2+15+8x+10[/tex]
Adding [tex]8x^2[/tex] and [tex]4x^2[/tex], so,
Perimeter of triangle = [tex]12x^2+15+8x+10[/tex]
This can be written as
Perimeter of triangle = [tex]12x^2+15+8x+10[/tex]
Adding 15 and 10,
Perimeter of triangle = [tex]12x^2+8x+25[/tex]
So, the correct choice is = [tex]12x^2+8x+25[/tex]
Hope this helps.
