the correct answer with stwps will be given BRAINLIEST ANSWER.​

Answer 1

Step-by-step explanation:

GIVEN:-

a=120m,

b=80m,

c=50m

TO FIND:-

THE AREA WHERE RAMU WILL PLANT THE TREE

FORMULA USED:-

HERON'S FORMULA ,

SEMIPERIMETER:

$\frac{a + b + c}{2}$

AREA OF TRIANGLE:

$\sqrt{s(s - a)(s - b)(s - c) }$

SOLUTION:-

$s = \frac{120 + 80 + 50}{2} = \frac{250}{2} \\ = 125$

$area = \sqrt{125(125 - 120)(125 - 80)(125 - 50} \\ = 375 \sqrt{15} m^{2}$
