Step-by-step explanation:
To find:- We have to find the area of the right angled triangle ?
☯️ In this question, the height of the triangle is not given. So, to find the area of the triangle first let us find out the height.

Answer:
Let ABC is a right angled triangle at B
Base=BC=6cm
HypotenuseAC=10cm
Using Pythagoras theorem,
AC

=AB

+BC

=AC

−BC

=10

=100−36
AB=

=8cm
Altitude=AB=8 cm
Now , Area of triangle =
