Let the length of the two equal sides be x cm each.
Given that the perimeter is the sum of the lengths of all three sides, we have:
6 + x + x = 22
Simplifying, we get:
6 + 2x = 22
2x = 16
x = 8
Therefore, the possible lengths for the other two sides are 8 cm each.
One reason for this is because in an isosceles triangle, the two equal sides must be of the same length. So, if one side is 6 cm, the other two sides must be equal, making them 8 cm each.
The perimeter of this isosceles triangle is 22 cm. If one side is 6 cm, what are the possible lengths of the other two sides?
