Step-by-step explanation:
The formula is L=√((3×V)/h)
By definition, the area of a rectangle is given by:

Where,
w: width
l: long
We then have the following area:

Factoring the area we have:

Therefore, according to the definition, two possible dimensions of the rectangle are:
Answer:
The area of the rectangle in factored form is:
One possible set of dimensions for this rectangle is:
Answer:
Step-by-step explanation:
Congruent parts of congruent triangles are congruent, so we can easily demonstrate BD ≅ DF ≅ BF.
<h3>Proof</h3>
AB ≅ BC ≅ CD≅ DE≅ EF ≅ FA . . . . definition of regular hexagon
∠A ≅ ∠C ≅ ∠E . . . . definition of regular hexagon
ΔFAB ≅ ΔBCD ≅ ΔDEF . . . . SAS congruence
FB ≅ BD ≅ DF . . . . CPCTC
ΔBDF is equilateral . . . . definition of equilateral triangle
