उत्तर
Steps of construction:
Step I: Draw DC = 5 . 1 cm .
\[\text { Step II: Construct} \angle DCB = 120^\circ . \]
Step III : With C as the centre and radius 6 . 8 cm, cut off BC = 6 . 8 cm .
Step IV: With B as the centre and radius 7 . 7 cm, draw an arc .
Step V : With D as the centre and radius 3 . 6 cm, draw an arc to intersect the arc drawn in Step IV at A .
Step VI: Join AB and AD to obtained the required quadrilateral .
