Question

if the base of right angled triangle is 15cm and hypotenuse is25cm find its area

Answer 1

Base = 15 cm

and Hypotenuse = 25 cm

So, Height = √25²  - 15² = √400 = 20 cm

So, Area = base*height/2 = 20*15/2 = 15*10 = 150 cm²

Answer 2

Base=15 cm.
Hypotenuse=25 cm.
So, (height (side))^2=(25)^2-(15)^2=100
So height=10cm.
Now area=1/2×base×height
=1/2×15×10=75 cm square.
