Question

In the given figure ABCD is a quadrilateral in which AB = BC angle B = 90° = angle D , AD =3 cm and CD= 4 cm find AD and calculate the area of ∆ABC.​

Answer 1

Answer:

6cm²

Step-by-step explanation:

Note: If opposite angles of a quadrilateral are of 90° then the quadrilateral will always be a rectangle.

so, AD = BC = 3cm

and DC = AC = 4cm

so area of a triangle is 1/2× base×height

= 1/2×3×4

= 12/2

= 6cm² .... ans.
