Answer: 9 would be the width of the cornfield. the area if both L and W doubled would be 252
Step-by-step explanation:
all you gotta do is divide 63 by 7 and you will get the width, 9.
formula: A/L=W
the area would be 252 if doubled both length and width because its multiplying 2 by 7 and 9, equaling to 14 and 18, which you multiply that together.

The height of the ramp (b)=10
Step-by-step explanation:
(arb)4 = 81r24
a4r4b = 81r24
a4 = 81
a = 4√81
a = 3
r4b = r24
4b = 24
b = 6
any more help just ask :)
The mass of the stand will be 21165 g.It is found as the product of the density and the mass of the stand.
<h3 /><h3>What is mass?</h3>
Mass is a numerical measure of inertia, which is a basic feature of all matter. It is, in effect, a body of matter's resistance to a change in speed or position caused by the application of a force.
The frustum shape volume is;
From the similarity;
The volume of the second section;
The volume of the stand is ;
Mass of stand = volume of stand × density of the stand
Mass of stand = 249 cm³ × 85 85 g/cm³
Mass of stand = 21165 gm
Hence, the mass of the stand will be 21165 g
