Answer 2

Answer:

489.89

Step-by-step explanation:

Heron's Formula = $\sqrt{s(s-a)(s-b)(s-c)}$

here, a, b , c are the sides of a triangle and s is the semi- perimeter.

So, here a = 50, b = 50  and c = 20

s = $\frac{a + b+ c}{2}$  =  $\frac{50 + 50+ 20}{2}$  = 60

s-a = 60 -50 =10 = s-b

s-c  = 60 - 20 = 40

Now, putting all values in the heron's formula, we get

area = $\sqrt{60(10)(10)(40)}$

       = $\sqrt{240000}$  = 489.89
