Question

Two sides of a triangle and of lengths 7cm and 3.5cm. The length of the third side of the triangle cannot be

a) 3.6cm

b) 4.1cm

c) 3.4cm

d) 3.8cm

Answer 1

Answer:

Option (c) 3.4 cm can not be third side of this triangle

Step-by-step explanation:

We know that in a triangle

Sum of two shorter sides > Third Side

here two sides given 7 cm and 3.5 cm

for Option (a)

3.6 + 3.5 = 7.1 which is greater than 7 (possible)

Option(b)

4.1 + 3.5 = 7.6 which is greater than 7 (possible)

Option(c)

3.4 + 3.5 = 6.9 which is not greater than 7 so it is not possible to have third side as 3.4 cm, hence option (c) is the correct option.
