Construct a rhombus PQRS such that PQ=3.2 cm and PR=4.2 cm.

Explanation

Steps:
1. Draw a line segment PQ=3.2 cm.
2. Taking P as the centre and radius equal to 4.2 cm, draw an arc , and taking Q as the centre and radius as 3.2 cm, draw another are to cut the previous arc at R.
3. With R and P as centres and the radii equal to 3.2 cm each, draw two arcs to meet at S.
4. Join PS,RS, and QR to form rhombus PQRS.
