**Ans. Given**: RE = 5.1 cm.

**To construct**: A square READ.

**Steps of construction**:

**(i)** Draw RE = 5.1 cm.

**(ii)** At point E, construct an angle of and draw an arc of radius 5.1 cm, which intersects at point A.

**(iii)** At point R, draw an arc of radius 5.1 cm at point A, draw another arc of radius 5.1 cm which intersects the first arc at point D.

**(iv)** Join AD and RD.

It is the required square READ.

**2. A rhombus whose diagonals are 5.2 cm and 6.4 cm.**

**Ans. Given**: Diagonals of a rhombus

AC = 5.2 cm and BD = 6.4 cm.

**To construct**: A rhombus ABCD.

**Steps of construction**:

**(a)** Draw AC = 5.2 cm and draw perpendicular bisectors on AC.

**(b)** Since, diagonals bisect at mid-point O, therefore get half of 6.4 cm, i.e., 3.2 cm.

**(c)** Draw two arcs on both sides of AC of radius 3.2 cm from intersection point O, which intersects at B and D.

**(d)** Join AB, BC, CD and DA.

It is required rhombus ABCD.
