Anna purchased a phone with a rectangular screen that measures 6,5 centimeters in width and 12 centimeters in length. She wants to know the diagonal measure of the screen. Round your answer to the nearest tenth of a centimeter
6.5 cm
12 cm

anywhere within 13.5 < cm < 14.5   ie) 13.7cm

Step-by-step explanation:

Pythagoras for all diagonals or right angle sides.

12^2 + 6.5^2 = c^2

sqrt 144 +  sq rt 42.25 = c^2

c^2 = sq rt 186.25 =  13.6473441  = 13.7cm

nearest 10th of a cm = 13.5<cm<14.5

the answer is c. 23/3

i think the answer is seven, for if i'm being useless °ω°
