Question

Find the perpendicular length of a right angled triangle whose hypotenuse is 15cm and base is 12 cm

Answer 1

I think answer will be =9 cm

Answer 2

You can just apply Pythagoras theorem i.e.
Hypotenuse ^2 = Base^2 + Height^2
15^2=12^2+ Height^2
Height^2= 225-144= 49
Height = 7.
So, Perpendicular length = 7 cm.
