A) 5, 12, 13
B) 10, 24, 26
C) 15, 36, 39
D) 20, 48, 52
Correct Answer: C
Solution :
Let sides be \[5x,\,12x,\,13x\]. Obviously the triangle is right angled. Hence \[\Delta =\frac{1}{2}\,(12x)\,(5x)\Rightarrow 30{{x}^{2}}=270\Rightarrow x=3\] Hence sides are 15, 36, 39.You need to login to perform this action.
