Question

Is it possible to form a triangle with the given side lengths? If not explain why not.

0.7, 1.4, 2.1

a. yes

b.no; 0.7 + 2.1 > 1.4

c. no; 2.1 + 1.4 > 0.7

d. no; 0.7 + 1.4 = 2.1​

Answer 1

d. no; 0.7+1.4=2.1 is the answer...

because for forming a triangle the sum of two sides should be greater than the third side always.

while in this case it is equal so it is not possible to form a triangle...
