Find the dimensions of a rectangle whose perimeter is 46 m and whose area is 126m

The length is 14 and the width is 9 or the length is 9 and the width is 14. Clue is that this:

46=2 (l+w)

Divide both sides by 2

23=l+w

Then u have to find a factor that if u multiply it is 126 that add up to 23 which is 14 and 9
