Solution
Steps of construction:
Step I: Draw QR = 2 . 5 cm .
Step II: Construct ∠PQR = 75° at Q . \]
Step III : With Q as the centre and radius 3 . 5 cm, cut off QP = 3 . 5 cm .
Step IV: Construct ∠QRS = 120° at R .
Step V : With R as the centre and radius 4 . 1 cm, cut off RS = 4 . 1 cm .
Step VI: Join PS
The quadrilateral so obtained is the required quadrilateral .
