Answer 1

Answer:

3rd Side =P-15

Step-by-step explanation:

Pshould be greater than 15

Answer 2

Answer:

The least and the greatest possible value of p is 21 and 28 cm.

Given:

One side of a triangle is 5cm and other side is 10 cm and its perimeter is p cm.

To find:

The least and the greatest possible value of p  

Solution:

In a triangle the sum of two sides is less than the third side.

Consider 5 and 10 cm as the two sides.

When 10 is the largest then the other must be at least 6.

The perimeter = 10 + 5 + 6 = 21 cm

I f the third side is the largest, then it should be less than 10 + 5 = 15,  

Hence it should  be 14, 10 + 5 + 14 = 29 cm

21 and 28 cm are the values of p.
