Question

1. The sides forming the right angle of a right angled triangle are 12 cm and 5 cm long. Find the area of the triangle.​

Answer 1

Answer:

The two sides of a right angled triangle forming the right angle are 5 cm and 12 cm  

Therefore, hypotenuse (third side of the right angle triangle) = sqrt of (5^2 + 12^2)

hypotenuse = 13 cm

radius of the circumcircle of the triangle = half the length of the hypotenuse

                                   

                                                               = 13/2  

                                         

                                                               = 6.5 cm
