Problem

If the perimeter of a scalene triangle is 25 inches and two sides of a triangle a and b are 10 inches and 4 inches respectively, find the length of the third side c.

2

Step

Given that

perimeter(p) is 25 inch a is 10 inch b is 4 inch

3

Formula

Perimeter of scalene triangle formula is P = a + b + c.

4

Step

Plug the values in the formula:

25 = 10 + 4 + c

5

Step

Here, we need to find out the (c) value:

25 = 14 + c

6

Step

After Simplification:

c = 25 - 14

c = 11 inch

7

Solution

Therefore, the third side of the scalene triangle is 11 inches.
