Area of Quadrilateral ABCD =
Step-by-step explanation:
In a quadrilateral ABC ,∠A = 90°,
AB=32 cm,AD=24 cm,BC=CD = 52 cm
Construction:
Join BD.
In ΔABD,∠A= 90°
As we know Pythagorean triplets (24,32,40)
So,BD = 40 cm
Also,
=
=
Now,For ΔBCD,As it is an isoceles triangle
Length of perpendicular drawn from point C on BD of ΔBCD
=
=
= 48 cm
Now
=
=
Area of quadrilateral ABCD =
=
Hence,Area of Quadrilateral ABCD =
