Anna is building a rectangular
picture frame. if the sides of the frame
are 20 inches by 30 inches, what should
be the diagonal measure? round to the
nearest tenth of an inch.

Diagonal is 36.06 inches

Step-by-step explanation:

Using Pathogoras' Theorem:

√(20²+30²) = 36.0555in

≈ 36.06in

(Correct me if i am wrong)

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
