To construct a quadrilateral PQRS with PQ = 5 cm, QR = 7 cm, RS = SP = 6.2 cm and the diagonal PR = 9 cm, the steps involved are written below:
(i) Draw a line PR = 9 cm.
(ii) With P as centre draw an arc with radius 5 cm.
(iii) With R as centre and radius 7 cm, draw an arc in the same side which intersects the arc at Q.
(iv) Join P and Q, Q and R, R and S, S and P.
(v) With P as centre and radius 6.2 cm, draw an arc on the side of PR opposite to that of Q.
(vi) With R as centre and radius 6.2 cm, draw another arc on the same side which intersects the arc at S.

A) i, ii, iii, vi, v, iv
B) i, ii, iii, iv, vi, v
C) iii, ii, i, v, vi, iv
