Question

(5ft 6in)x4 equals what

Answer 1

Step-by-step explanation:

first of all, something like

5 ft 6 in

is always actually a short form of an addition :

5 ft + 6 in

so,

(5 ft 6 in) × 4 = 5×4 ft + 6×4 in = 20 ft 24 in

but 1 ft = 12 in.

that means that the 24 in are actually 2 ft.

and so, the fully cleaned-up answer is

20 ft + 2 ft = 22 ft (0 in)
