I see you could not be bothered to study the url I gave you earlier. I'll do most of your work for you.
the area of the triangle, found using the method of your choice, is 2310
so, the radius of the excircle is (68+75+77)/2 - 68 = 2310/42 = 55
thus, the circle's area is 3025π
hope that's right; you can double-check my math.
a triangle has sides equal to 68 cm, 77 cm and 75 cm, respectively. find the area of the escribed circle tangent to the shortest side of the triangle.
