Heron's Formula - Area of Isosceles Triangle
Heron's Formula for Area of Triangle - There are many types of question based on heron's formula. But basically, whenever we see, if there is only perimeter known or we know only the sides of the triangle, in such every cases we have to use Heron's Formula to find the area of the triangle. In this geometry question related to finding the area of the isosceles triangle , we are given the perimeter of the triangle and the two equal sides of the isosceles triangle, so with this much given things we need to find the area of the isosceles triangle easily using heron's formula.
Before applying heron's formula we need the semi perimeter and every sides so first we have to find the 3rd side by subtracting the sum of the rest two sides. Once we get all the three sides then we use Heron's formula easily to find the area of the triangle.
