Question

If two sides of a triangle are 8cm and 6cm and its perimeter is 26 cm. Find the 3rd side of the triangle?​

Answer 1

add 8 centimetre and 6 centimetre and then subtract from 26cm

Answer 2

Answer:

In a triangle sum of length of the either of the two sides of a triangle is always greater than the third side so third side will be less then sum of the length of two given sides i.e.(6+8=14cm) and also the difference of the length of either of two sides will be less than the third side so, third side will be greater than the difference of these two (8-6=2cm)

so, third side will be greater than 2cm and less than 14cm
