Problem |
If the perimeter of an equilateral triangle is 120 feet and two of the sides are 40 feet, what is the length of the third side? |
|
2 |
Step |
The perimeter of triangle is given(P) |
60 feet |
3 |
Step |
The length of the two sides of a triangle is given, |
40 feet |
4 |
Formula |
Perimeter of the triangle |
P = a + a + a P = 3a |
5 |
Step |
Now, we have to find the third side of a triangle is |
P - (a + a) = a |
6 |
Step |
Substitute the values |
120 - (40 + 40) = a a = 120 - 80 |
7 |
Step |
After subtraction |
a = 40 |
8 |
Step |
The length of the third side is 40 feet. |
