Rectangle of a Given Area

Background

The idea for this task came from a GCSE Maths past paper that asked students to draw (on a grid) a rectangle with an area of 21cm². The key to doing this is to factorise the area - e.g. 21 is 7 x 3, so a rectangle that measures 7cm by 3cm will have an area of 21cm².

If you'd like a diagram to help you to see what's going on, then I have created another page to help you to visualise the concept.

Your Task

Create a function that:

• takes a number as an argument - this represents the area of the rectangle
• returns the dimensions of at least one possible rectangle that would have that area

As an extension you might like to return the dimensions of the squarest rectangle, or the one with the longest perimeter.
