So many stemcell indians got mad for this question because they couldn't solve it
so I am posting the solution
looksmax.org
For convenience lets say
∠BCA = ∠c
∠CAD = ∠a
∠ADE = ∠b
We know that angle sum of a sides of 5sides is 540 degree
and angle
∠ABC+∠ADC+∠DAE = 180degree,
∠BAC + ∠ACD+ ∠AED = 180degree,
we can get the remaining angle ∠c + ∠a + ∠b
The sum of angle of whole - (∠ABC+∠ADC+∠DAE) - (∠BAC + ∠ACD+ ∠AED) =
which is 180 degree.
Now here is the creative trick
everybody knows that the angle of a straight line is 180 degrees.
We can flip the triangle ABC and Triangle ADE
to make the angle c,a,b coincide in one point and make a straight line.
Thus we had 5sides but not it turns into 4sides making it simpler but still
maintaining it's area.
INow we re label the points of new 4-sided shape as a,b,c,e
and the angles.
We can extend the line ae and bc until it conincides and if we say that coinciding point as d
and we can know that the triangle abc and triangle ecd are both
isoceles triangle and similar to each other.
So if we use the ratio we know the length of ad = 96cm
Now the last to step is to get the area by subtracting the area of
triangle abd and the area of triangle ecd.
You can get the height of each isoceles triangle using pythagoras.
The required knowledge is basically elementry middle school level
but requires high creativity

Anybody smart with math???? come here.
There are lots of currycells here who study days to day on math. I see bunch of Muh Jee Advanced in math youtubes everywhere muh we have the smartest IT workers. I just found a mind blowing geometry question that looks complicated but could be also solved in only one simple calculation. Let...
