Construct a rectangle PQRS in which cm and diagonal cm. Measure the other side of the rectangle.

STEP 1: At first draw a base line of 3.6 cm.

STEP 2: Draw a perpendicular line to QR from Q.

STEP 3: Now from R draw an arc of radius 6 cm on the perpendicular line by compass. The intersecting point is P.

STEP 4: Join PQ. This is the other side of the rectangle. Measure its size with scale.

By measuring the length of PQ by scale, we get, PQ = 4.8 cm.

STEP 5: Draw an arc of radius 3.6 cm from P and draw an arc of radius 4.8 cm from R, intersecting at a same point. This point is S. Join PS and RS.
