Answer 2

Answer:

Step-by-step explanation:

This formula is called herons formula

For this first we have to calculate semi perimeter i.e. s

S = sum of all sides of triangle /2

= 120 + 170 + 250 / 2

= 540 / 2

= 270

Now a is first side

b is second side

c is third side

Now area of triangle

s( s - a) (s - b) ( s - c) whole under root

Now put all the values over here and u will get the answer........

Hope it would help uh
