Core 1 Inequalities Problem Solving question?

Jo is designing a rectangular pool.
The perimeter is to be 100m and the area is to be at least 525m^2.


Work out the possible values for the width of the pool.

Answer is:

The width must be greater than or equal to 15m and less than or equal to 35m



I ALWAYS seem to get stuck on problem solving questions :frown::frown:

Thanks..

OK, area = l * w
so 525 = 100 * w
so 525/100 = w
so w = 52.5 except for the fact that it could be less than or equal to that.
so w < (or equal to) 52.5
