27/2=13.5(radius)
area: pi*r*r=
pi*13.5*13.5=
572.55526
rounded, 572.56
circumference: 2*pi*r(which is basically diameter times pi)

there are two expressions that can represent the length of the rectangle, these two expressions are:
L = x
or
L = (4x + 12)
<h3>
Which expression could represent the length of the rectangle?</h3>
Remember that for a rectangle of length L and width W, the area is given by:
A = L*W
In this case, we know that the area is:

We can factorize that expression into:

So there are two expressions that can represent the length of the rectangle, these two expressions are:
L = x
or
L = (4x + 12)
