To find the second moment of area about the x axis use
Ix = /int y^2 dA
To find the second moment of area about the y axis use
Iy = /int x^2 dA
In this video I solve this problem using the double integral method (which is more robust). However, this can also be done using a single variable if we choose a strip of area dA = b*dy
