Question

Determine whether a triangle can be formed with the given side lengths. If so, use Heron’s formula to find the area of the triangle.

a = 240
b = 121
c = 263

Answer 1

to check if the given side lengths form a triangle or not :-
sum of any two sides must be greater than the third side

Answer 2

All below must hold :
a+b > c
b+c > a
c+a > b

then, the side lengths will form a triangle

Answer 3

well i know it can form a triangle cuz those are all true

Answer 4

good :)
next use the heron's formula and find the area

Answer 5
