Answer 1

The perimeter of the isosceles triangle is 24 inches.

Explanation:

Given that the length of the two equal sides of the triangle is $6\frac{1}{2} \ inches = \frac{13}{2} \ inches$

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;

$Perimeter= \frac{13}{2}+\frac{13}{2}+11$

                 $= \frac{13+13+22}{2}$

                 $=\frac{48}{2}$

$Perimeter = 24 \ inches$

Thus, the perimeter of an isosceles triangle is 24 inches.
