Astudent would like to find the height of a statue. the length of the statue's right arm is 48 feet. the student's right arm is 2 feet long and her height is 5 1/3
feet. use this information to find the height of the statue. how close is the approximate height to the statue's actual height of 128 feet, 3 inches from heel to top of head?

Explanation:

This problem is about proportions. A proportion  an equality between two ratios.

In this case, you assume that the ratio of length of the student's right arm and his height is equal to the ratio of the statue's right arm and its height.

Let's use the following variables to work more neatly:

Proportion:

Convert the mixed number into improper fraction:

Continue with the proportion:

Thus, the calculated height of the statue is 128 feet.

Error:

To determine how close is the approximate height to the statue's actual height of 128 feet, 3 inches from heel to top of head, calculate the difference (absolute error):

So, the absolute error is 3 inches.

You can also calculate the percent error:
