R triangle

Calculate the right triangle area whose longer leg is 6 dm shorter than the hypotenuse and 3 dm longer than the shorter leg.

Correct answer:

S =  158.9 dm2

Step-by-step explanation:

c2=a2+b2 a=c6 a=b+3 a>0 b>0  b226b26362=0  b=6+262+263=16.39 dm a=b+3=19.39 dm  S=12ab=12(b+3)b=158.9 dm2
