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

The given rectangle PQRS can be drawn as follows:

Step 1: Draw a line segment QR = 3.6 cm.

Step 2: Draw RX perpendicular to QR

Step 3: With 6 cm from Q draw an arc cutting RX at S

Step 4: Join RS

Step 5: With 3.6 cm from S draw an arc.

Step 6: With R as centre and radius equal to QS draw another arc, cutting the previous arc at P.

Step 7: Now, join PQ and PS.

PQRS is the required rectangle.

To find the other side, we will use the Pythagoras theorem

= 4.8 cm
