1 |
Problem |
Find the height of an equilateral triangle if its perimeter is 31 units. |
|
2 |
Step |
The given perimeter of the triangle is |
31 units |
3 |
Formula: |
The height of an equilateral triangle is |
\$Height = \sqrt (3) /2 times perimeter /3\$ |
4 |
Step |
Substitute the given values in the formula |
\$Height = \sqrt (3) /2 times (31) /3\$ |
5 |
Step |
After simplification |
\$Height = 0.866 times 10.33\$ |
6 |
Step |
After simplification |
Height = 8.945 units |
7 |
Step |
The height of an equilateral triangle is Height = 8.945 units |
