A rectangular page is to contain 95 square inches of print. the margins on each side are 1 inch. find the dimensions of the page such that the least amount of paper is used.

Hey

Let the dimensions for the Print Region be M, N

Additional Margin is summed up to get:

New Dimensions of the Page = (M + 2) (N)

[ 2 inches - 1 inch on either side ]

Hence, the Area = [ MN + 2N ] = [ 95 + 2N ]

Note that 'N' has to be a factor of 95

=> Least Possible Area is achieved when N = 5

=> Dimensions of the Page = { 21 inches x 5 inches ]
