284 mm^2

Step-by-step explanation:

We observe that the figure is made up of 2 squares and 1 triangle.

Lets consider the bigger square.

We observe that it sides are 12 mm

Hence, its area would be the square of its sides and hence, 144 mm^2.

Lets now consider the smaller square.

We observe that it sides are 7 mm

Hence, its area would be the square of its sides and hence, 49 mm^2.

Now,

Lets take the triangle into consideration.

We observe that,

One of its segments is not given to us and needs to be computed;

Lets take the length of this segment as x

Hence,

As the one of the sides of both the squares sum up to the lengths of the segment and 8,

We now find its:

Base = 3+11 =14 mm

Height = 13mm

Hence, its area would be :

Hence,

The Sum of the total figure = Sum of Areas of both the squares and that of the triangle

Hence,

The Sum of the total figure =

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
