Question
The base of a right angled triangle is 5cm and hypotenuse is 13cm. Find its area.
Hint:
Use Pythagoras theorem
The correct answer is: 30 cm2
It is given that base, B = 5 cm and hypotenuse, H = 13 cm
Using Pythagoras theorem
H2 = B2 + P2
132 = 52 + P2
169 – 25 = P2 ⇒ P2 = 144
⇒ P = 12 cm
Area of triangle =
= 30 cm2
