A function that models area of an isoceles triangle.
The model we want is a function that gives the area of an isosceles triangle.
Let x be the length of two equal sides of an isosceles triangle and b is given the length of its base.
Because of the perimeter of the triangle is the sum of all sides and it is 8.
Subtract b from both sides,
Divide by 2,
Let h be the length of the altitude to the base.
Therefore, the area A of the isosceles triangle is given by
Thus, the area A of the isosceles triangle modeled by the function
The area of the isosceles triangle modeled by the function
