we have that

the scale is

1 in=2 ft

the area of the bed in the drawing is

(2 1/8)*(3 1/4)

Convert to an improper fraction

2 1/8=2+1/8=17/8 in

3 1/4=3+1/4=13/4 in

Convert in to ft according the scale

Remember that

1 in=2 ft

so

17/8 in=(17/8)*2=17/4 ft

13/4 in=(13/4)*2=13/2 ft

Multiply to obtain the actual area

(17/4)*(13/2)=221/8 ft^2

Convert to mixed number

221/8=216/8+5/8=27+5/8=27 5/8 ft^2

answer is 27 5/8 ft^2

option D
