Question

Jorge wants to determine the enlarged dimensions of a digital photo to be used as wallpaper on his computer screen. The original photo was 800 pixels wide by 600 pixels high. The new photo will be 1,260 pixels wide. What will the new height be?
460 pixels
945 pixels
1,680 pixels
1,860 pixels

Answer 1

The best answer would be 945 pixels high.

Answer 2

Answer:  Second option is correct.

Step-by-step explanation:

Since we have given that

Width of original photo = 800 pixels

Height of original photo = 600 pixels

Width of new photo = 1260 pixels

Let height of new photo be 'h'.

So, it becomes,

$\dfrac{800}{600}=\dfrac{1260}{h}\\\\\dfrac{600\times 1260}{800}=h\\\\\dfrac{756000}{800}=h\\\\h=945\ pixels$

Therefore, height of new photo is 945 pixels.

Thus, Second option is correct.
