Note: Myy B.M coming negative as 80kN(D) and 600kN(A) taking as compression side but it results in tension

enter image description here

[1] Area of footing = $(2 + 2) \times (1 + 1) = 8 m^2$

Section modulus about XX – axis = $\frac{\frac{bd^3}{12}}{(\frac{d}{2})} = \frac{bd^2}{6}$

$( Z = \frac{I}{Y})$

$= \frac{4 \times 2^2}{6} = 2.67 \ m^3$

Section modulus about YY – axis = $\frac{db^3}{6} = \frac{2 \times 4^3}{6}$

= …
