Question

rict a quadrilateral ABCD, where AB = 3 cm, BC = 4 cm, CD = 5 cm, AC = 6.5 cm and
4. Construct a a
BD = 7.5 cm.​

Answer 1

Answer:

Abc=ab+bc

=3+4

=7

Abc=7

Answer 2

rict a quadrilateral ABCD, where AB = 3 cm, BC = 4 cm, CD = 5 cm, AC = 6.5 cm and  4. Construct a a  BD = 7.5 cm.​

Hence the required construction of quadrilateral ABCD.

Steps of construction:

Draw a line AB with a scale of 3 cm.

From a point B draw an arc with a scale of 4 cm

From a point A draw an arc with a scale of 6.5 cm such that, this arc intersects with the arc drawn from point B.

Mark a point of intersection of arcs  from points A and B as C.

From point C draw an arc of length 5 cm.

From a point B draw an arc with a scale of 7.5 cm such that, this arc intersects with the arc drawn from point C.

Mark a point of intersection of arcs  from points C and B as D.

Hence the required quadrilateral ABCD.
