Answer:
Use heron's formula for solving this question
Heron's formula =
A = √(s(s-a)(s-b)(s-c)) , where
s = Semi-perimeter of the triangle = ((a+b+c)/2)
a,b,c are the sides of the triangle
For the given triangle, let a = 17cm, b = c = 25cm
s = (a+b+c)/2 = (67/2) = 33.5cm
A = √(33.5*(33.5-17)(33.5-25)(33.5-25))
= √(33.5 * 16.5 * 8.5 * 8.5)
= √(39936.1875)
= 199.84 cm² (approx.)
