Let L = length & W= width
Just rewrite the problem in math:
L=5+2W & Area = L x W=403cm²===> (5+2W).(W)=403.
==>2W²+5W-403 =0 Solve the quadratic equation. & you will get W=13
Plug it to find L =31
Answer:
Yes, it is a rational number.
Step-by-step explanation:
Rational numbers are numbers that can be written as a fraction or ratio no matter if it is proper or improper.
Example: Take π for example. Since it goes on forever, it cannot be written a s a fraction or ratio. Therefore it is irrational.
Ending: Therefore, since this can be changed into a fraction, 5 1/5 is rational.
