If X=3, What is the area of a triangle with sides, 6x, 7x, and 21x? A. 117 in² B. 378 in² C. 189 in² D. 58.5 in²

The given sides does not form a triangle

Step-by-step explanation:

The given sides does not form a triangle

We know the triangle property which states that the sum of any two sides of the triangle should be greater than the third side.

Here given th esides of the triangle are 6x, 7x, 21x

6x+7x=13x < 21x

for any value of x the above equation does not satisfy.
