A triangle with sides 12, 16 and 20 units is given.
Statement 1: To find the area of this triangle, the formula "Area=12×base×height" is the ideal one to be used.
Statement 2: To find the area, the formula "Area=√s(s−a)(s−b)(s−c)" is the ideal one to be used.
Enter “1” if you feel Statement 1 is correct, or “2” if Statement 2 is correct.
Observe that 122+162=144+256=400=202, i.e., this triangle is right-angled, with 20 units as the hypotenuse and the other two sides forming the base and the height.
So,
Area of a triangle=12×base×height
is the ideal one to proceed.
