There are 12 inches in every foot.

The length and width will increase by a factor of 12.

The area will increase by a factor of 144, since area is length times width.

Note:

The area is the same, except hat it is expressed in different units.

The area is

(11 ft) * (13 ft) = 143 ft²

In inch-units, the area is

(11*12 in) * (13*12 in)

= (12*12) * (11*13)

= 144*143

= 20,592 in²
