Answer -
Given: Here from the given figure we get
(1) ABCD is a quadrilateral with base AB,
(2) ΔABD is a right angled triangle
(3) ΔBCD is a right angled triangle with base BC right angled at B
To Find: Area of quadrilateral ABCD
Calculation:
In right triangle ΔBCD, by using Pythagoreans theorem
In right triangle ABD
Hence we get Area of quadrilateral ABCD =
