Each dimension is in the scale 1:20 That means each real length is 20 times the drawing size.
mathstudent55
  • mathstudent55
First, what is 4 inches * 20 ? 5 inches * 20 ?
anonymous
  • anonymous
So just think of the scale as a fraction 1 over twenty or 1/20

  • anonymous
Exactly just multiply by 20

@mathstudent55 its 80 and 100

Yes

Correct. The real dimensions of the room are 80 inches and 100 inches. Now we need to find the area. Since the room is a rectangle, you use the formula for the area of a rectangle A = LW

100 x 80 ?
mathstudent55
  • mathstudent55
Yes. What do you get?
moazzam07

8000
mathstudent55
  • mathstudent55
A = 100 in. * 80 in. = 8000 in.^2 Now we have the are in square inches. The problem wants the are in square feet, so we need to convert.

We need to figure out how many square inches there are in a square foot.

A square 1 ft by 1 ft has an area 1 ft * 1 ft = 1 square foot. 1 foot = 12 inches, so A square 12 inches by 12 inches has an area 12 in. * 12 in. = 144 square inches. This shows that 1 square foot = 144 square inches

  • moazzam07
would i do 8000 / 12?
mathstudent55
  • mathstudent55
Ok, now we need to convert 8000 square inches into square feet. We know the conversion factor is 144. The question we have is do we multiply 8000 by 144 or do we divide 800 by 144? We can figure it out by reasoning it out. 1 square foot is the same size as 144 square inches. This means that 1 square foot is much larger than a square inch, so much so that it takes 144 square inches to equal 1 square foot. That means that for the same are, it will take many more square inches to fill it up than square feet. Then, if we divide the number of square inches by 144, we get square feet. \(A = LW = 80 ~in. \times 100~ in. = 8000 ~in.^2\) \(A = \dfrac{8000}{144}~ft^2 \)

Divide 8000 by 144, not by 12.
