How to Find the Area of an SAS Triangle

  • The formula for the area of a triangle with two sides and an included angle is: Area = ½(b)(c)(sin A)

Given the following:

  • A = 72º
  • b = 21
  • c = 15

Plug in the values into the formula:

Area = ½(b)(c)(sin A)

Area = ½(21)(15)(sin 72)

Area of triangle = 149.8 units²
