<PRE><B>Question 49513</B>
Data Given:
Right Angle Traingle
Hypotenuse = 25 cm
One leg = 15 cm

Let C=Hypotenuse = 25 cm
One leg = A = 15 cm
Other leg = B ( to be claculated before calculating area)

In a right angle traingle , according to Pythagorean theorem,

C^2 = A^2 + B^2

25^2 = 15^2 + B^2

625 = 225 + B^2

625 - 225 = B^2

400 = B^2

Therefore B = Sqrt of 400 = 20

Area of a Right angle triangle = (One leg * Other leg) / 2

That is  Area = (A * B) / 2 = (15 * 20)/2 = 300/2 = 150 Square cm
