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 = 302

Yes, the triangle can be formed with the given side lengths and it would have an area of 13,724.27 squared units.

Step-by-step explanation:

So first, yes, a triangle can be formed because the sum of the smaller sides is greater than the biggest side.

So first, Heron's formula consists on two parts:

which is half of the perimeter of the triangle.

And the area formula itself:

we know that a=240, b=121 and c=302

so we can start by calculating s.

Once we got s, we can plug it into the given formula:

which yields:

when solving the parenthesis we get:

which simplifies to:

so the answer is:

A=13 724.27 squared units.

the answer is  

c.
