उत्तर
Steps of construction:
Step I: Draw AB = 3 cm .
Step II: Construct ∠ ABC = 120° .
Step III : With B as the centre and radius 3 cm, cut off BC = 3 cm .
Step IV: With C as the centre and radius 5 cm, draw an arc .
Step V : With A as the centre and radius 5 cm, draw an arc to intersect the arc drawn in Step IV at D .
Step VI: Join AD and CD to obtained the required quadrilateral .
