Question

A scale drawing of a building has the scale 0.5 in. 6 ft a wall is 30 ft long. How long will the wall be on the drawing.

Answer 1

can you clarify that problem is confusing to read

Answer 2

does that help

Answer 3

so .5 inches = 1 foot?

Answer 4

and you want to know how long a 30 foot wall and a 6 foot wall would be if drawn to the scale .5 in = 1 foot. am i understanding you correctly?

Answer 5

I think so

Answer 6

first you set up a ration of .5 in = 1 foot ( 12 in) therefore .5 in = 12 in. So the 30 foot wall has 360 inches in real life so you set .5 in = 12 inches and x in = 360 in and solve for x and you get x=15 which means that in your drawing a 30 foot wall will be represented by a 15 in line

Answer 7

You solve the other wall of 6 feet lenght by doing the same steps

Answer 8

can you just write all that in numbers because I can't understand words.

Answer 9

I guess it is this way.
6 feet of real building is represented by 0.5 inches in the drawing.
1 foot = 12 inches
6 feet = 6*12=72inches
30 feet = 30*12=360 inches
Let us assume that 30 feet is represented by x inches in the drawing.
\[0.5:72=\frac{0.5}{72}\]
\[x:360=\frac{x}{360}\]
\[\frac{x}{360}=\frac{0.5}{72}\]
Find x. Does that help? @Maddie1234

Answer 10

Is it really necessary to convert the wall dimensions to inches. When the scale is stated as .5 in = 6 ft. Then it is given that a wall is 30 ft long. You need only to find how many 6 ft increments are contained in 30 ft. That would be 5. So now you only need 5 times the .5 in. So the drawing will need to only be 5(.5) or 2.5 (2 1/2 in.) long.

Answer 11

To say it with numbers then, let x = the required length on the drawing:

x (.in) =(30/6) (.5 in)

Answer 12

By the way, there is nothing wrong with ajprincess's approach, if you desire to convert all the building dimensions to inches.
