उत्तर
Steps of construction:
Step I: Draw BC = 3 . 6 cm .
Step II: Construct ∠ABC = 30° at B .
Step III : With B as the centre and radius 4 . 2 cm, cut off BA = 4 . 2 cm .
Step IV: Construct ∠BCD = 150° at C .
Step V : With C as the centre and radius 4 . 8 cm, cut off CD = 4 . 8 cm .
Step VI: Join AD .
The quadrilateral so obtained is the required quadrilateral .
