Construct a rectangle ABCD whose adjacent sides are 11 cm and 8.5 cm.
Steps of Construction:
(i) Draw a line segment AB = 11 cm.
(ii) At B, draw a perpendicular and cut off BC = 8.5 cm.
(iii) With centre A and radius 8.5 cm and with centre C and radius 11 cm, draw arcs intersecting each other at D.
(iv) Join AD and CD.
ABCD is the required rectangle.
