As, the length is 6 cm longer than the width, so the length will be:

Formula for the Area of rectangle is:

Given that, the area of a rectangle is 72 cm²

So....

Using zero-product property, we will get...

(Negative value is ignored as width can't be negative)

and

So, the width of the rectangle is 6 cm.
