Here is your answer dear..

have a nice day..

Answer 2

Answer:

5853.204 m²

Step-by-step explanation:

if the sides of a triangle be a,b,c

then area is √(s(s-a)(s-b)(s-c)

where s is (a+b+c)/2

s = (100+120+140)/2 = 180m

area = √(180)(180-100)(180-120)(180-140)

= √(180)(80)(60)(40)

= √34560000

= 5853.204 m²
