C-16-Q007mediumsingle_mcq

In a right-angled triangle with legs $a$ and $b$ adjacent to the right angle, the area equals —

a $ab$
b $\dfrac{1}{2}ab$
c $\dfrac{1}{2}\sqrt{a^2 + b^2}$
d $\dfrac{ab}{\sqrt{a^2+b^2}}$

ব্যাখ্যা

In a right triangle the two legs are mutually perpendicular, so one leg serves as base and the other as height. The area is therefore $\tfrac{1}{2}ab$ .
