Two columns 50 cm x 50 cm and 60 cm x 60 cm carry 80 tonnes and 120 tonnes of loads respectively. The centre to centre distance between columns is 5.00 metres. The permissible bearing capacity of the soil is 20 t/m². If the footing is not to project more than 25 cm beyond the outside of the smaller column, pick up the correct design parameters of the footing from the following:

distance of C.G. of the loads from the smaller column = 3.00 m

the length of the foundation slab = 7.00 m

area of footing slab = 11.00 m²

width of the footing = 1.57 m.

all the above.
