Answer 1

A. 14

Explanation:

Answer 2

14.14inches

Explanation:

Given data

Length L= 10 inches

Width W= 10 inches

The size of the screen is described by the lenght of the diagonal

Applying the Pythagoras theorem we have

D^2= L^2+ W^2

D^2= 10^2+ 10^2

D^2= 100+100

D^2= 200

D= √200

D= 14.14 inches

Hence the size of the screen is 14.14inches
