A right triangle with hypotenuse c=25 dm is given. Calculate the length of the unknown side, given: side a=15 dm. Find the area of this triangle. Sketch the triangle and describe all its vertices and sides correctly.

Final Answer:

S =  150 dm2

Step-by-step explanation:

c=25 cm a=15 dm  c2 =a2+b2  b=c2a2=252152=20 dm  S=2a b=215 20=150 dm2
