A rectangle is 10 inches long and 8 inches wide, what is the length of the diagonal?

Step 1. Use the Pythagorean Theorem where the sum of the squares of the legs (length and width) is equal to the square of the hypotenuse (diagonal).

Step 2. Let d be the diagonal, then d%5E2=10%5E2%2B8%5E2

d=sqrt%28100%2B64%29

d=12.81 ANSWER

I hope the above steps were helpful.
