Find the perimeter of an isosceles triangle whose equal sides measure

6 1/2 inches and whose third side measures 11 inches.

Answer 1

The perimeter of the isosceles triangle is 24 inches.

Step-by-step explanation:

Given that the length of the two equal sides of the triangle is
`6(1)/(2) \ inches = (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= (13)/(2)+(13)/(2)+11`

`= (13+13+22)/(2)`

`=(48)/(2)`

`Perimeter = 24 \ inches`

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