The area of a rectangle is length times width or l*w or lw so the length being 22 cm and width 14 cm 22*14 = 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
