Answer:

Here's ur answer mate..

Step-by-step explanation:

Pls refer the attachment for the same...

PQ= 6 units

RS= 6 units (3 units on +x axis whereas -3 units on -x axis)

Therefore, PQ= RS= 6 units

PS= 3 units (starting from  -1 to -4 on -y axis)

QR= 3units (starting from 5 to 2 on +y axis)

Therefore, PS= QR= 3 units

Hence, PQRS is a rectangle as its opposite sides are equal. [PROVED]
