Given three sides $a = 15, b = 25, c = 12$

Area of the triangle can be found using the formula

$A_t = sqrt (s * (s-a) * (s-b) * (s-c)), "where " s = (a + b + c ) / 2$

$s = (15 + 25 + 12) / 2 = 26$

$A_t = sqrt(26 * (26 - 15) * (26 - 25) * (26 - 12))$

$color(blue)(A_t = sqrt (26 * 11 * 1 * 14) = 63.28 "sq units"$
