Math Question - Scale Drawings?

Question

I need help with a question.

1) Lauran decides to build a storage shed for his stuff. He makes a drawing of the shed using a scale of 0.5 inch : 1 foot. If She wants a window in the shed, and decides it will be 2 feet wide, how wide should the window be in her scale drawing.

2) Margret suggests to Lauran that the floor of the shed in her scale drawing shuld be 12 inches by 18 inches. What would the real demensions of the floor be? [Use the same scale as problem 1]

Also, may you teach it in Proportions. And show your work. I really don't get the scale drawings, and my test over it is 2 days after today.

btw, i know the answer 2 number one, it's 1 inch....right?

If possible...

ex:
1/4 = x/5
5=4x
5/4=1.25 , 4x/4 = x
X=1.25

Answer 1

Problem one's answer is 1 inch as you guessed.

Problem two, the answer is : 24 by 36 feet
Here is how to get it...
As seen in the previous problem, each inch on the paper is 2 feet in real dimensions.
so we just multiply each inch by 2.

Answer 2

divide the first numbers 6 into 12 gives 2, so the second figure is twice as long as the first. then divide the 18 by 9, that is also 2, so the second figure is twice as tall. the ratio of the ares is the product of these two numbers, or 2 times 2 is4. so the area of the second rectangle is 4 times the area of the first. You can actually count the squares, there are 54 squares in the first figure and 216 in the second ( or four times as many)

Answer 3

your answer for the first question is right the second question would be 24x36 you simply multiply the 12x18 by 2 with this particular scale
