Hello, dolly kohli!

Obviously, some information is missing . . .

can you solve this sum for me --- sum?

PQRS is a quadrilateral.

Sides RS and QR are the same length.

Sides QP and RS are parallel.

Calculate:

With no more information, it is impossible to answer the questions . . .

Code:

P Q
o * * * * * * * * * o
θ * *
* θ *
* * *
* * *
* * θ *
o * * * o
S R

Since is isosceles.

. . Hence: .

Since

Since can be anywhere to the upper-left on that line,

. . we cannot determine

Nor can we find the lengths of and , or the area of .
