Question

a rectangle bookcase 60 inched long and 30 inches wide. how long is the diagonal? round to the nearest inch

Answer 1

B. 67 inches

Explanation:

Answer 2

It will be roughly 67.08 inches.

We can solve this using the Pythagorean Theorem, which is listed below.

`a^(2) + b^(2) = c^(2)`

In this equation, we use a and b as legs of a triangle and c is the hypotenuse. We can treat the length and height of the bookcase as legs and use this equation to solve for the diagonal (also known as the hypotenuse)

`30^(2) + 60^(2) = c^(2)`

`900 + 3600 = c^(2)`

`4500 = c^(2)`

67.08 = c
