Question

The width and height of a computer screen are 16 inches and 30 inches respectively. What is the screen size? (Hint: Screen size is the length of the diagonal of the screen.)​

Answer 1

Answer:

Screen size = 46 inches

Step-by-step explanation:

According to the information provided in the question it is given as

Width = 16 inches

Height= 30 inches

we need to find the screen size

Diagonal = $\sqrt{} w^{2} + l^{2}$

Putting the values we get diagonal

[tex]D = \sqrt{} 16^{2} + 30^{2} \\ D= 16 +30\\ D= 46 inches [/tex]

Hence the diagonal of computer screen is 46 inches  is nothing but the screen size

$\large\underline{\sf{ \implies \sqrt{ {16}^{2} + {30}^{2} } }}$

$\implies \large\underline{\sf{16 + 30}}$

$\implies \large\underline{\sf{46inches}}$
