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 = 127
c = 281

  area of the triangle is about 15,183.766

Step-by-step explanation:

The sum of the two shortest sides is 367, which is greater than the longest side, hence these side lengths can form a triangle.*

The perimeter is ...

  p = 240 +127 +281 = 648

so the semi-perimeter is ...

  s = p/2 = 648/2 = 324

Heron's formula tells you the area is ...

  A = √(s(s -a)(s -b)(s -c)) = √(324·84·197·43) = √230,546,736

  A ≈ 15,183.766

The area of the triangle is about 15,183.766 square units.

_____

* The terms s-a, s-b, and s-c are all positive, which is further evidence the side lengths will form a triangle. If one or more of those factors is negative, the side lengths will not form a triangle.

answer: 59

step-by-step explanation:

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.
