Question

You are designing a web page for your school's biology club. You wantto include photos of the members on the page, which has a width of640 pixels. You've decided that the left and right margins should be 24pixels each and the space between each picture should be 16 pixels.How wide can each picture be to fit four across the width of the page?

Answer 1

Given that:

Width of the page = 640 pixels

Size of the left margin = 24 pixels

Size of the right margin = 24 pixels

Space between each picture = 16 pixels

Number of pictures = 4.

Then the number of spaces between 4 pictures is 3. So, the space needed between the four pictures

`\begin{gathered} =(4-1)\cdot16 \\ =3\cdot16 \\ =48 \end{gathered}`

Width in the page remaining for pictures

`\begin{gathered} =640-24-24-48 \\ =544 \end{gathered}`

Width of the picture

`\begin{gathered} =(544)/(4) \\ =136 \end{gathered}`

Thus, the wide of a picture that can be fit four pictures on the page is 136 pixels.
