The largest possible print area is

Step-by-step explanation:

Represent the dimensions of the poster with x and y

So:

Make x the subject

The top and bottom margin which are: 5cm and 8cm respectively, implies that 2 times each measurement of each dimension will be removed to get the print area.

So, the dimension of the print space is:

x - 10 by y - 16

Print Area is;

Substitute in

Open Bracket

Different w.r.t y

To get y, we have to set:

So:

Add 10 to both sides

Cross Multiply

Divide both sides by 10

Take square roots

Recall that:

Also, recall that the print area is calculated using:

So:

Hence, the largest possible print area is
