Question

Carol bought a coloring book. It is 11 inches long and 8 inches wide. What is the diagonal length of the book?

Answer 1

Answer:

13.6 inches

Step-by-step explanation:

We can use Pythagorean theorem: $c=\sqrt{a^{2} +b^{2} }$

Let c be the diagonal length, a for length, and b for width.

Substitute the values.

$c=\sqrt{11^{2}+8^{2} }$

c=13.6 inches
