Problema Solution
A layout artist wants to have 270 cm^2 of graphic art on a page that measures 20 cm by 28 cm. if the bottom border of the page must be 3 times as deep as the borders on the other three sides, how wide should each border be?
Answer provided by our tutors
let
w = the depth of the border on 3 sides, w>0
3w = the depth of the bottom page border
the area of the page without the borders should be equal to 270 cm^2:
(28 - 2w)(20 - (3w + w)) = 270
by solving we find:
w = 2.15 cm

the 3 borders should be 2.15 cm each
the bottom border should be 3*2.15 = 6.45 cm.
