  A triangular park has sides measuring 150 meters, 120 meters, and 90 meters. Calculate the area of the park using Heron's formula. Remember, Heron's formula for the area � A of a triangle with sides of lengths � a , � b , and � c and semiperimeter � s is given by: A = s × ( s − a ) × ( s − b ) × ( s − c ) ​ where � = � + � + � 2 s = 2 a + b + c
