Question

A right angled triangle has the largest side as 13 cm and one of the sides containing the right angle as 12 cm. Its area in cm is?​

Answer 1

A right angled triangle has the largest side as 13

Answer 2

Answer:

let the triangle be ABC

AC=13

AB=12

BC= X

By Pythagoras theorem

AC²=AB²+BC²

13²=12²+X²

169=144+X²

169-144=X²

25=X²

5²=X²

5=x

BC=X=5

Area of traingle = 1/2xbxh

=1/2x5x12

= 60/2

= 30cm²
