# A screen

A screen is 1680 x 1050 pixels. What are the coordinates (and size in pixels) of an centered area which is exactly 33% of the screen size?

Correct result:

a =  965
b =  603
x0 =  357
y0 =  223
x1 =  2037.4567
y1 =  223.4105
x2 =  2037.4567
y2 =  1273.4105
x3 =  357.4567
y3 =  1273.4105

#### Solution:

${x}_{0}=w\mathrm{/}2-a\mathrm{/}2=1680\mathrm{/}2-965.0865\mathrm{/}2=357$
${y}_{0}=h\mathrm{/}2-b\mathrm{/}2=1050\mathrm{/}2-603.1791\mathrm{/}2=223$
${x}_{1}={x}_{0}+w=357.4567+1680=2037.4567$
${y}_{1}={y}_{0}=223.4105$
${x}_{2}={x}_{0}+w=357.4567+1680=2037.4567$
${y}_{2}={y}_{0}+h=223.4105+1050=1273.4105$
${x}_{3}={x}_{0}=357.4567$
${y}_{3}={y}_{2}=1273.4105$ We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you! Tips to related online calculators
