Solution

The correct option is A

Statement 1 is true and Statement 2 is false.


In a right-angled triangle, two sides containing right angle is the perpendicular and the base.

Area of the triangle = 12 × base × height

= 12 × base × perpendicular

= Product of the two sides containing right angle2

Statement 1 is true.

In Heron’s formula ‘s’ stands for semiperimeter.

Hence, Statement 2 is false.
