Answer 2

Answer:

The diagonal should be approximately: 36.1

Step-by-step explanation:

The diagonal is the hypotenuse for a right triangle with sides 20 inches and 30 inches.

Set up the equation:

c^2 = a^2 + b^2

c^2 = 20^2 + 30^2

c^2 = 400 + 900

c^2 = 1300

c = 36.055 rounded to 36.1 inches
