a. If the screen’s height is 21 inches, what is the width of the screen?
b. The border around the screen is 2 inches. What are the dimensions of the television, including
the border?

Answer 1

Explanation:

d^2=h^2+w^2

a)

w^2=42^2-h^2, h=21

w^2=1764-441

w^2=1323

w=36.373

b)

36.373+2(2) by 21+2(2)

w=40.373, h=25
