Let the width=x
Length =6x-4
As we know that in a rectangle
- Substitute the values
- Here a=6, b=-4, c=-20.
- use quadratic formula
For this case, the first thing we must do is define variables:
x: unknown number (1)
y: unknown number (2)
We now write the equations that model the problem:
their sum is 6.1:
their difference is 1.6:
Solving the system we have:
We add both equations:
Then, we look for the value of y using any of the equations:
Answer:
