The Answer is 14 cm if i look at it correctly

The area of a rectangle is length times width or lw or lw
so the length being 22 cm and width 14 cm
2214 = 308 cm
the area of the dance floor is 308 square cm of the scale drawing...

it says that 5cm in the scale drawing is 8 ft in reality...
so 35.2 ft and 22.4 ft are the new length and width respectively
so 35.2 times 22.4 is the actual floor area
788.48 ft

Hope this helps ;)
