Solution
In right angled triangle ABC having base 5 cm and hypotenuse 13 cm we are asked to find its area
Using Pythagorean Theorem
Where, AB = hypotenuse = 13 cm, AC = Base = 5 cm, BC = Height
Area of a triangle, say A having base 5 cm and altitude 12 cm is given by
Where, Base = 5 cm; Height = 12 cm
Therefore, the answer is (c).
