What Is The Perimeter Of The Triangle Below W Solution class=

Sagot :

PERIMETER OF A TRIANGLE

==============================

» Sides of the triangle.

  • (2x² + 7) cm
  • (3x² - 2x) cm
  • (x² + 12x - 5) cm

» Formula.

[tex]\sf \large \blue{Perimeter_∆ = Side_1 + Side_2 + Side_3}[/tex]

» Find the perimeter of the triangle.

[tex] \sf \big \blue{Perimeter_∆ = Side_1 + Side_2 + Side_3}[/tex]

[tex] \sf \big Perimeter_∆ = (2x² + 7) + (3x² - 2x) + (x² + 12x - 5)[/tex]

[tex] \sf \big Perimeter_∆ = 2x² + 7 + 3x² - 2x + x² + 12x - 5[/tex]

[tex] \sf \big Perimeter_∆ = 2x² + 3x² + x² + 12x - 2x + 7 - 5[/tex]

[tex] \sf \big Perimeter_∆ = 6x² + 10x + 2[/tex]

[tex] \sf \large \purple{Perimeter_∆ = 2(3x² + 5x + 1)}[/tex]

Final Answer:

[tex]\tt \Large » \: \purple{Perimeter_∆ = 2(3x² + 5x + 1) cm}[/tex]
