Problema Solution
A page of a magazine contains 70 square inches of type. The height of the page is twice the width. If the margin around the type is 2 inches uniformly, what are the dimensions of the page? Set up a quadratic equation and solve this problem.
Answer provided by our tutors
let
x = the width
2x = the height
2x*x = 70
by solving the quadratic equation we find
x = 5.92

the margin around the type is 2 in uniformly thus the dimensions of the page are
width: x + 2*2 = 5.92 + 4 = 9.92 in
height: 2x + 2*2 = 2*5.92 + 4 = 15.84 in
