If the length of a combined footing for two columns $$l$$ meters apart is L and the projection on the left side of the exterior column is x, then the projection y on the right side of the exterior column, in order to have a uniformly distributed load, is (where $$\overline {\text{x}} $$ is the distance of centre of gravity of column loads).
A. $${\text{y}} = {\text{L}} - \left( {l - \overline {\text{x}} } \right)$$
B. $${\text{y}} = \frac{{\text{L}}}{2} + \left( {l - \overline {\text{x}} } \right)$$
C. $${\text{y}} = \frac{{\text{L}}}{2} - \left( {l + \overline {\text{x}} } \right)$$
D. $${\text{y}} = \frac{{\text{L}}}{2} - \left( {l - \overline {\text{x}} } \right)$$
