Problem |
If the perimeter of a scalene triangle is 25 inches and two sides of a triangle a and b are 10 inch and 4 inch respectively, find the length of the third side c. |
|
2 |
Step |
Given perimeter(p) is a is b is |
25 inches 10 inches 4 inches |
3 |
Formula: |
Perimeter of scalene triangle is |
P = a + b + c |
4 |
Step |
Substitute the values |
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 = 11 inches |
7 |
Step |
Therefore, the third side of scalene triangle is 11 inches. |
