Find the area of the triangle whose vertices are A(4,4),B(3,-16) and C(3,-2)

The vertices of a triangle are A(4, 4), B(3, -2) and C(-3, 16). The area of the triangle is

If [{:(4, -3), (2, 16):}] = [{:(4, -3), (2, 2'):}] then t =____.

If a=3-sqrt(5) then the value of a^(4)-a^(3)-20a^(2)-16a+24

1-(3)/(16)+(1.4)/(1.2)((3)/(16))^2- (1.4.7)/(1.2.3)((3)/(16))^3 + …..=
