Answer:
We will be solving this question using an assumed value, the important thing is to know how to go about solving problems like this.
Explanation:
The scale is:
1/2 inches = 4 feet
This simply means that for every 1/2 inches we draw, the actual measurement is 4 feet.
Now, let us assume that the pole in the drawing measures 5 inches, its actual measurement will be calculated as follows:
1/2 inches = 4 feet
5 inches = x feet
x is what we are solving for.
The next step is to cross multiply, this gives us the following:
1/2 * x = 4 * 5
we therefore have:
1/2x = 20
next is to divide both sides by 1/2, we have
x = 20 divided by 1/2
doing this on a calculator gives us:
x = 40
Therefore, if the pole is 5 inches in the drawing, its actual length is 40 feet
