Question

What is the largest square of which the dimensions are natural numbers that you can cut from the corners of 20cm x 20cm paper? Explain

Answer 1

So let's cut out an x by x square from each corner.
so the base we would be left with would be an
(20-2x) by (20-2x) cm
but 20-2x > 0
-2x > -20
x < 10,

since you want x to be a natural number, that would be a 9 by 9 cm square
