Assume you have 60 feet of fencing or border material. Calculate the area of an isosceles triangle with a base of 12 ft.
I'm a little confused by this because if the base is 12 then obviously the remaining two sides will be 24 ft each.
When I construct an isosceles triangle, it is not possible to have the side lengths be 24 while also having the base angles be 45 degrees each. So how would I calculate the area of this triangle? What would the lengths be of the two congruent sides?
