Step-by-step explanation:
I wish if I could explain you with steps but this is the question I've never done with steps. I always give direct answers from those questions !!
Answer:
Um.. Im not sure about this one.. you're in college?
Step-by-step explanation:
The length of the rectangle is = 72 cm
The width of the rectangle is = 56 cm
Area of the rectangle is = 
=
cm²
As given, the other rectangle has the same area as this one, but its width is 21 cm.
Let the length here be = x


Hence, length is 192 cm.
We can see that as width decreases, the length increases if area is constant and when length decreases then width increases if area is constant.
So, in the new rectangle,constant of variation=k is given by,
or 
Hence, the constant of variation is 
3/4 is greater than 2/5. 2/5 is .4 and 3/4 is .75
