The correct option will be : B) 6 cm.
<u><em>Explanation</em></u>
Suppose, the width of the rectangle is
cm.
As, the length is 6 cm longer than the width, so the length will be: 
<u>Formula for the Area of rectangle</u> is:
Given that, the area of a rectangle is 72 cm²
So....

Using zero-product property, we will get...
<em>(Negative value is ignored as width can't be negative)</em>
and

So, the width of the rectangle is 6 cm.
180=90+50+x
180=140+x
x=180-140=40
X=40
Answer:
52 marbles i think
Step-by-step explanation:
They are easy to compare if they all have the same common denominator, then you can easily order them by the magnitude of the numerators...
85/10, -67/10, -56/10, 82/10 so now they are easy to compare...so
-6.7, -28/5, 8.2, 17/2
