The tangent plane equation of tangent plane is
z = x - 6y -1
This is further explained below.
What is the equation of the tangent plane to the surface z=ln(x-6y) at the point(7,1,0)?
Generally, Given surface is z = ln(x − 6y) ,
Given point is = (7, 1, 0)
partially differentiating with respect to x
== >zx = [1/(x - 6y)] (1) = 1/(x - 6y)
zx (7 , 1 , 0) = 1/(7 - 6(1)) = 1
Partially differentiating with respect to y
zy = [1/(x - 6y)] (-6)
zy = -6/(x - 6y)
zy(7 , 1 , 0) = -6/(7 - 6(1)) = -6
Equation of tangent plane is z - = zx(x -
) + zy(y -
)
z - 0 = 1(x - 7) + (-6)(y - 1)
z = x - 7 -6y + 6
z = x - 6y -1
In conclusion, equation of tangent plane is z = x - 6y -1

Firstly, we will draw figure
now, we will draw a altitude from B to DC that divides trapezium into rectangle and right triangle
because of opposite sides of rectangle ABMD are congruent
so,
DM=AB=9
CM=CD-DM
CM=18-9
CM=9
now, we can find BM by using Pythagoras theorem
now, we can plug values
we get
now, we can find area of trapezium
now, we can plug values
and we get
so, area of of the trapezoid is ..........Answer
