In the scale the bedroom's size would be 10 cm long and 6 cm wide, and the door's width would be 1.6 cm. In turn, the real bed size is 2m by 1.5 m.

Since Elena wants to make a scale drawing of her bedroom, and her bedroom is a rectangle with length 5 m and width 3 m, and Elena's bedroom door is 0.8 m wide, and Elena's bed measures 4 cm and cm on the scale drawing, If the scale is from 1 to 50, to determine the dimensions of the bedroom and door scale, and the actual dimension of the bed, the following cross multiplication calculations must be performed:

  • Room size = 10 cm long and 6 cm wide
  • 50 = 5
  • 1 = X
  • 5/50 = X
  • 0.1 = X
  • 0.1m = 10cm
  • 50 = 3
  • 1 = X
  • 3/50 = X
  • 0.06 = X
  • 0.06m = 6cm

  • Door width = 1.6 cm
  • 50 = 0.8
  • 1 = X
  • 0.8 / 50 = X
  • 0.016 = X
  • 0.016m = 1.6cm

  • Bed size = 2m by 1.5m
  • 1 = 4
  • 50 = X
  • 50 x 4 = X
  • 200 = X
  • 200 cm = 2 m
  • 1 = 3
  • 50 = X
  • 50 x 3 = X
  • 150 = X
  • 150cm = 1.5m

Therefore, in the scale the bedroom's size would be 10 cm long and 6 cm wide, and the door's width would be 1.6 cm. In turn, the real bed size is 2m by 1.5 m.
