Anna takes a rectangular piece of fabric and makes a diagonal from one corner to the opposite corner. The diagonal cut is 26 inches and the length is 24 inches. What is the width of the rectangular piece of fabric, rounded to the nearest tenth if necessary?

10 inches

Step-by-step explanation:

To solve the above question, we use the formula:

D² = L² + W²

Where

D = Diagonal = 26 inches

L = Length = 24 inches

W = Width

Hence:

W² = D² - L²

W = √D² - L²

W = √26² - 24²

W = √676 - 576

W = √100

W = 10 inches

Therefore, the width of the rectangular piece of fabric is 10 inches.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
