Area of
Explanation:
We will solve it using Co-ordinate Geometry.
Let us take
Also,
the resp. axes.
Since lengths
we have
Clearly,
We note that diagonal
With
the eqn. of line
Similarly, eqn. of line
Now,
Likewise,
Thus, in
Therefore, Area of
Hence, Area of
B., Sir!
Area of
Explanation:
I have solved this problem with the help of Co-ordinate Geometry. Now, I have been able to find its solution using only Geometry and a little bit of Trigonometry.
We know from Trigo. that,
the Area of
In
Similarly, from
We observe that, diagonal
Hence, by the
Arguing on the same lines,
In the light of
We have, from
Therefore, by
Area of
