HELLLPPPP!!!!!!!!!!!!!! I WILL MAKE YOU BRAINLIEST!!!!!!!!!! PLEASE HELP ME!!!

Find the area and perimeter. Hint: The height of a non-right triangle is the length of the segment of a line that is perpendicular to the base and that contains the opposite vertex.

12x; 5x + 14 12x;

7x + 3 24x;

10x + 8 24x;

5x + 14

Answer:

  • A. 12x; 5x + 14

Step-by-step explanation:

Perimeter is:

  • P = a + b + c
  • P = 4x - 3 + x + 9 + 8 = 5x + 14

Area is:

  • A = 1/2bh
  • A = 1/2*8*3x = 12x

Correct choice is A

[tex]\\ \sf\longmapsto Perimeter=Sum\:of\:sides[/tex]

[tex]\\ \sf\longmapsto Perimeter=4x-3+x+9+8[/tex]

[tex]\\ \sf\longmapsto Perimeter=5x+14[/tex]

And

[tex]\\ \sf\longmapsto Area=\dfrac{1}{2}base(height)[/tex]

[tex]\\ \sf\longmapsto Area=\dfrac{1}{2}(3x)(8)[/tex]

[tex]\\ \sf\longmapsto Area=12x[/tex]
