Question

The base of right triangle is 15cm and its hypotenuse is 25cm then its area is​

Answer 1

Step-by-step explanation:

BY PYTHAGORAS THEOREM

Altitude= 20

so, Area= 1/2*b*h

= 1/2*15*20

= 150cm sq

Answer 2

Step-by-step explanation:

By using hypothenus theorem, we get the height of triangle =(25)^2 - (15)^2

=625-225

=400

So, (lenght)^2=400

Lenght=20cm

Area of triangle =1/2×20×15

=150CM^2
