Question

find the area of quadrilateral ABCD in which AB=3cm,BC=4cm, CD=4cm,DA=5cm,AC=5cm​

Answer 1

Answer:

⇒  Draw a line segment AB=4cm

⇒  Take A as center with radius 5cm and draw an arc.

⇒  Take B as center with radius 3.1cm and draw an arc which cuts off previous arc at point C

⇒  Take A as center with radius 4.2cm and draw an arc.

⇒  Take C as center with radius 3.cm and draw an arc which cuts off previous arc at point D

⇒  Join BC,AC,CD,AD and BD

⇒  Measure the length of BD

⇒  We get, BD=5cm
