Question

a right angled traingle has hypotenuse 13 cm long . one of its side is 12 cm . what is the area​

Answer 1

Step-by-step explanation:

Base = 12

perpendicular = √13^2-12^2 = √25 = 5

so Area = 1/2× base × perpendicular

Area = 30

Answer 2

Answer:

30 cm².

Step-by-step explanation:

Let the right triangles be ABC which is right angled at B,the if we use pythagoras theorem,we could get the other side as 5 cm and if we apply the formula,1/2×base ×height=1/2×12×5,then we could get the answer as 30cm².

ok.
