Question

The moment of inertia of a thin square plate abcd of uniform thickness

Answer 1

Hey mate,
I suspect you want to know moment of inertia of square plate.

● Answer-
1/6 ml^2

● Explanation-
Let m be mass of the square plate and l be side length.

Moment of inertia of thin uniform square plate about axis passing through its centre and perpedicular to plane is given by -
Io = 1/6 ml^2

# Extra information-
Moment of inertia of square about its diagonal is -
Id = 1/12 ml^2

Hope this helps...
