`(x)/(a) +(y)/(b)+(z)/(c)=1` intersects the co-ordinate axes at points A ,B and C respectively. If `Delta PQR` has mid-points A,B and C then find area of `Delta PQR`

A tangent having slope of -(4)/(3) to the ellipse (x^(2))/(18)+(y^(2))/(32)=1 intersects the major and minor axes at points A and B, respectively.If C is the center of the ellipse,then find area of triangle ABC.

The plane x/a+y/b+z/c=1 meets the coordinaste axces in points A,B,C respectively. Find the area of /_\ABC .

The plane (x)/(2)+(y)/(3)+(z)/(4)=1 cuts the co- ordinate axes in A,B,C: then the area of the Delta ABC is

The plane lx+my+nz=p intersects co-ordinate axes at A,B and C .If area of Delta ABC is Delta ,then

If the plane (x)/(2)+(y)/(3)+(z)/(4)=1 cuts the coordinate axes in A,B,C, then the area of triangle ABC is

If the plane x/1 + y/2 + z/3=1 meets the co-ordinate axes in the points A, B and C, then area of triangleABC in sq. units is
