Answer :
The perimeter of the isosceles triangle is 24 inches.
Explanation:
Given that the length of the two equal sides of the triangle is [tex]6\frac{1}{2} \ inches = \frac{13}{2} \ inches[/tex]
The third side of the triangle measures 11 inches.
We need to determine the perimeter of the isosceles triangle.
Perimeter:
The perimeter of the triangle can be determine by adding all the three sides of the triangle.
The formula is given by
Perimeter of a triangle = Sum of all the three sides of the triangle
Substituting the values, we have;
[tex]Perimeter= \frac{13}{2}+\frac{13}{2}+11[/tex]
[tex]= \frac{13+13+22}{2}[/tex]
[tex]=\frac{48}{2}[/tex]
[tex]Perimeter = 24 \ inches[/tex]
Thus, the perimeter of an isosceles triangle is 24 inches.
