Answer:
Step-by-step explanation:
Let, the length of the rectangle be 'L'
and, width of the rectangle be 'W'
length=2*Width+3
Area of the rectangle= 90 square feet
Area of a rectangle = Length*Width
Using Factorization Method to solve quadratic equation:
Taking common from the equation:
OR
The Width cannot be negative, therefore Width(W)=12 feet
Here is the equation:
Since both decimals are negative, the answer will be positive.
- Negative times Negative = Positive
Divide both sides by -3.9 to leave the variable alone:
r is equal to 4 → r = 4
