Ответ:
21.26 or 21.3 inches.
Step-by-step explanation:
Think of this as a right triangle.
The height is 16 inches.
The width is 14 inches.
So, the diagonal is...
We need to use the Pythagorean Theorem to solve this.
a^2 + b^2 = c^2
Height^2 + Width^2 = Diagonal^2
16^2 + 14^2 = c^2
256 + 196 = c^2
c^2 = 452
So, c = Square root of c^2 = Square root of 452.
So, Square root of 452 = 21.26
So, the diagonal = 21.26 or 21.3 inches.
