Question

A triangle has side lengths of 14 cm and 7 cm. Which could be the value of the third side, 22 cm or 20 cm?

Answer 1

22 is false because 14+7
So the correct choice would be 20

Answer 2

20 cm

Explanation:

When you add the lengths of any two sides in a triangle, it has to be greater than the length of the third side.

So...

14 + 7 > side 3

14 + 7 > 22 is false

14 + 7 > 20 is true
