[tex]\large\underline\bold{PROBLEM:}[/tex]

  • The floor plan of a room has scale 2.5 in : 35ft. In the drawing the length of the room is 8 in. and the width of the room is 6 in. What is the perimeter of the actual room?

[tex]\large\underline\bold{SOLUTION:}[/tex]

» In the drawing, the length of the room is 8 in, and the width of the room is 6 in, so the perimeter in the drawing is:

  • P = 2(8 + 6)
  • P = 2(14)
  • P = 28 in

» Since the scale is 2.5 in : 35 ft thus, the perimeter (P) in the actual room is:

  • 2.5/35 = 28/P
  • P = (28)(35)/2.5
  • P = [tex]{\boxed{\green{\sf{392ft }}}}[/tex]
