Question

a standard sheet of white lined paper measures 8.5 inches by 10 inches to the nearest tenth of an inch , what is the length of the diagonal

Answer 1

The length of the piece of paper diagonally is 13.1 inches.

Explanation:

First, I decided to imagine the diagonal line as the hypotenuse of a right triangle, and use the Pythagorean Theorem, a^2 + b^2 = c^2.

In this case, it would be 8.5^2 + 10^2 = ?^2.

8.5^2 = 72.25, and 10^2 = 100.

72.25 + 100 = 172.25, which equals c^2.

However, since 172.25 inches is c squared and not just c, we need to find the square root of it, which is 13.1, rounded to the nearest tenth.

Hope this helps.

Answer 2

im pretty sure its 37 because

8.5 x 2 = 17 10 x 2 = 20
then add
17 + 20 = 37 :)) hope this helps

(you multiply by 2 because on a sheet a paper there 4 sides on the paper and two for each number)

37 is your awnser :))
