Question

In the triangular sheet given PQ = QR = l. If M is the mass of the sheet. What is the moment of inertial about PR

$\frac{M l^{2}}{24}$
$\frac{M l^{2}}{12}$
$\frac{M l^{2}}{6}$
$\frac{M l^{2}}{18}$

The correct answer is: $fraction numerator M l to the power of 2 end exponent over denominator 12 end fraction$
