51.36 is the answer.
The equation is total=original(1+% in decimal form)
A
This is like a base form of a prime polynomial
X^2+x+1
The area of a rectangle is calculated as length times its width. So, for the given area above, the expression should b written as:
20 = LW
To know the length for various measurement of the width, we can write it by:
L = 20 / W
You can substitute any measurement to W and you can obtain the corresponding value of the length.
