Radius of circle =8cm and
Altitude =6cm
Since, in a right-angled triangle the hypotenuse is the diameter of circumcircle. (given)
This implies,
Hypotenuse =2(Radius)
=2×8
=16
⇒ Hypotenuse =16cm
Area of a triangle =12×Base×Height
(Consider hypotenuse as base and the altitude to the hypotenuse as height)
=12×16×6
=48
⇒ Area of a triangle =48cm2
