The area is 11317.51

Step-by-step explanation:

The sum of 2 sides must be less than the third side (largest side) for a triangle to be formed.

b+c
133+174 < 240

A triangle can be formed

To use Herons formula for the area

We find S = 1/2 (a+b+c)

= 1/2 (240+133+174)

= 1/2 (547)

= 273.5

Area = sqrt (S (S-a) (S-b) (S-c))

sqrt ((273.5) (273.5 - 240) (273.5-133) (273.5-174))

sqrt ((273.5) (33.5) (140.5) (99.5))

sqrt (128085964.4)

11317.50699

The area is 11317.51
