# Question #f9011

##### 2 Answers

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 **Lee

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
