Please need help with the second question and if not hard also the third ^)
WILL GIVE BRAINLEST

Here's the solution :

1. The given figure is of a Rectangle, and we know that diagnonals of a Rectangle bisects each other.

so, PR = 2 × PT

that is :

and both the diagnonals of a Rectangle are equal,

2. let's take the length of PQ = x and QR = y

Angle RPS = Angle PRQ = 60°

(because they form pair of Alternate Interior angles, which are equal)

By using trigonometry :

similarly,

And now, we know that area of triangle PQR is equal to :

3. Area of Rectangle PQRS :
