**Question 1: **Draw a rectangle PQRS in which PQ = 7.2 cm and QR = 5.4 cm.**Solution:** Steps of construction:

**I.** Draw a line segment PQ = 7.2 cm.**II.** At P, draw such that ∠QPS = 90°.**III. **From PX, cut off PS = 5.4 cm.**IV. **At Q, draw such that ∠PQY = 90°.**V.** From QY, cut off QR = 5.4 cm.**VI.** Join R and S.

Thus, PQRS is the required rectangle.**Question 2:** Draw a quadrilateral in which AB = 4.5 cm, BC = 5.1 cm, CD = 3.9 cm, ∠B = 90° and ∠C = 120°.

**Solution: **Steps of construction:**I. **Draw a line segment AB = 4.5 cm.**II.** At B, construct ∠ABX = 90°.**III.** From cut off BC = 5.1 cm.**IV. **AT C, drawsuch that ∠BCY = 120°.**V. **From, cut off CD = 3.9 cm.**VI.** Join AD.

Thus, ABCD is the required quadrilateral**Question 3:** Draw a square ABCD such that AB = 6.3 cm. **Solution:** Steps of construction:

**I. **Draw = 6.3 cm.**II. **At B, draw , such that ∠ABX = 90°.**III.** From cut off BC = 6.3 cm.**IV.** With centre C and radius = 6.3 cm, draw an arc.**V. **With centre A and radius = 6.3 cm, draw another arc to intersect the previous arc at D.**VI.** Join DA and CD.

Thus, ABCD is the required square.
