Question

two sides of a triangle are of length 7 cm and 2.8 cm. The length of third side of a triangle cannot be
1. 4.5 cm
2. 5.2 cm
3. 6.2 cm
4. 4.1 cm


PLEASE ANSWER THIS QUESTION WITH EXPLANATION..​

Answer 1

Answer:

4) 4.1cannot be the third side because sum of two smaller sides should be greater than the third side

it is given that

first and greater side =7cm

then sum of two other sides should be greater than the third side

when we add 2.8cm with given third sides

we get that

2.8+4.5=7.3

2.8+5.2=8

2.8+6.2=9

but 2.8+4.1= 6.9

so sum of two smaller sides is not greater than third side that's why is cannot be the third side
