Draw a rectangle PQRS in which PQ = 7.2 cm and QR = 5.4 cm.
First of all make a rough sketch. Do not start construction without drawing a rough sketch showing sides, angles and diagonals, etc., with correct name.
Step I. Draw a rough sketch and mark the measurements.
Step II. Draw AC = 7 cm.
Step III. With A as centre and radius 4 cm, draw an arc above AC.
Step IV. With C as centre and radius 6 cm, draw another arc intersecting the previous arc at B.
Step V. With centre A and radius 5.5 cm, draw an arc below AC.
Step VI. With centre C and radius 5 cm, draw another arc to intersect the previous arc at D.
Step VII. Join DA and DC.
Thus, ABCD is the required quadrilateral.
Steps of construction:
I. Draw a line AB = 4.5 cm.
II. With centre A and radius = 2.6 cm, draw an arc.
III. With centre B and radius = 4.5 cm, draw another arc such that it intersects the previous arc at D.
IV. With centre D and radius = 5 cm, draw an arc.
V. Again with centre B and radius = 3.2 cm, draw another arc to intersect the previous arc at C.
VI. Join AD, BC and DC.
Thus, ABCD is the required quadrilateral.
