Question

Find the area of a right angled triangle if its longest side is 13cm and one of the
other side is 5cm.​

Answer 1

Answer:

ab/2=13×5/2=65/2=32.5

Answer 2

Answer:

We know that longest side is hypotenuse of triangle i.e. = 13cm

other side can be base ,or height

let it be base =5 cm

therefore by Pythagoras theorem

the height = 12 cm

Area of triangle is = 1/2 *( base *height )

= 1/2*(5*12)

= 1/2*(60)

= 30 cm square
