Question

The base of a isosceles triangle is L centimeter and its perimeter is x centimeter . Find the area of the triangle

Answer 1

I think you should check the question twice.
because we know that the area of the isosceles triangle = ½×base of the isosceles triangle× height of the isosceles triangle.
And I can't find the height of the isosceles triangle in your question.
If the height of the isosceles triangle is "h" then
we can write the area of the triangle is = ½Lh
