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

H^{2} = B^{2} + P^{2}

13^{2} = 5^{2} + P^{2}

169 – 25 = P^{2} ⇒ P^{2} = 144

⇒ P = 12 cm

Area of triangle =

= 30 cm^{2}
