First we draw a rough sketch of quadrilateral ABCD. Draw a diagonal AC and write down its dimension in rough figure.

Steps of Construction
(i) First of all, draw a line segment AB = 4.5
cm.
(ii) With B as centre draw an arc of 5.5 cm. and with A draw an arc of 7.0 cm. Write the name C at the intersection point of both arc. Join AC and BC.

(iii) With A as centre draw an arc of 6 cm and with C as centre draw an arc of 4 cm. Now name point D to the intersect point of both arcs. Join AD and CD. Thus, ABCD is the required quadrilateral.
