Question

1/2 * PRODUCT OF LENGTHS OF SIDES FORMING A RIGHT ANGLED TRIANGLE
=> 1/2 * 40 CM * 30 CM
=> 20 CM * 30 CM
=> 600 CM^2

Answer 1

Explanation:

Area of a triangle = 1/2 × base × altitude

=1/2 × 40cm × 30cm

=20cm × 30cm

=600cm²

i.e., it is true

Now,

base of the right angled triangle= 40cm

altitude or perpendicular =30cm

Therefore

Hypotenuse = √(30² + 40²)

=√(900 + 1600)

= √2500 =50cm
