Detailed Solution

Given, the value
AB=5.8 cm Diagonal AC=8.2 cm
Diagonal BD=6.2 cm
We construct a figure stepwise as,
First of all make a  line AB = 5.8 cm.
1st In OAB,
OA=12AC=12×8.2 cm=4.1 cm.   {Since, A parallelogram diagonal bisect each other]
OB=12BD=12×6.2 cm=3.1 cm.
So draw an arc from A as center with measure 4.1 cm and from B as center with measure 3.1. Give name O to the intersection point of arcs and join A and B to O.
2nd AO produce up to C
OC=OA=4.1cm
And BO produces up to D
DO=OB=3.1 cm
So, extent AO to C such OC=4.1 and OB to D such that DO= 3.1.
3rd we have to joined AD, DC and CB.

This figure is parallelogram opposite sides are equal and parallel.
Correct option is 1.
